  1. AOption (a)

    Average family income

  2. BOption (b)

    Total income of a country

  3. COption (c)

    Total income divided by population

  4. DOption (d)

    Government income

View answer & explanation

Correct answer

Answer: (c)C.

Total income divided by population

Why this answer is correct

The correct answer is Total income divided by population.

Key Points

  • Per Capita Income (PCI), also known as average income, is a fundamental economic metric used to measure the amount of money earned per person in a specific geographic area like a nation or city.
  • It is calculated by taking the Total National Income of a country (often measured as Gross National Income or Net National Income) and dividing it by its Total Population.
  • The concept is vital for determining the Standard of Living and the quality of life of the people in a country, as it helps identify the average individual's purchasing power.
  • The World Bank utilizes this metric in its annual World Development Report to categorize countries into different economic groups such as Low-income, Lower-middle income, Upper-middle income, and High-income countries.
  • In international comparisons, Per Capita Income is often adjusted for Purchasing Power Parity (PPP) to account for the differences in the cost of living and inflation rates across different nations.

 Additional Information

  • Average family income:
  • Refers to the Household Income, which is the combined gross income of all members of a household aged 15 and older. While relevant for micro-economic analysis, it does not represent the national average per person.
  • Total income of a country:
  • Commonly referred to as the Gross Domestic Product (GDP) or National Income. It represents the total value of all finished goods and services produced within a country's borders in a specific time period but does not account for the size of the population.
  • Government income:
  • Known as Public Revenue, this consists of money received by the government from various sources including Direct Taxes, Indirect Taxes (like GST), fines, fees, and dividends from Public Sector Undertakings (PSUs). It is used to fund public expenditure and Infrastructure Development.

Key Points

  • The Bharatiya Nyaya Sanhita (BNS), 2023, which replaced the colonial-era Indian Penal Code (IPC) of 1860, officially introduced Community Service as a distinct form of punishment under Section 4.
  • This reformative measure is designed to address petty or minor offences, allowing the judiciary to penalize offenders without sentencing them to prison, thereby reducing jail overcrowding and preventing first-time offenders from mixing with hardened criminals.
  • According to the BNS, community service is defined as work that the court orders a convict to perform for the benefit of the community, for which the offender is not entitled to any remuneration.
  • Specific instances where this punishment can be applied include misconduct in public by a drunken person (Section 355), defamation, and attempt to commit suicide to compel or restrain a public servant from discharging their duty.
  • In cases of theft where the value of the stolen property is less than 5,000 rupees and the offender is a first-time convict, the court has the discretion to award community service upon restitution of the property or value.

 Additional Information

  • Bharatiya Nyaya Sanhita (BNS), 2023:
  • It received Presidential assent on December 25, 2023, and officially came into force on July 1, 2024.
  • The act streamlined the criminal code from 511 sections in the IPC to 358 sections in the BNS.
  • Legal Framework for Punishment:
  • The BNS lists six types of punishments: Death, Imprisonment for Life, Imprisonment (Rigorous or Simple), Forfeiture of Property, Fine, and Community Service.
  • The implementation of community service is often supervised by a Magistrate or an officer designated by the State Government.

Liberalization

Why this answer is correct

The correct answer is Liberalization.

Key Points

  • Liberalization refers to the relaxation or removal of government-imposed restrictions on economic activities to promote a more market-oriented environment.
  • It specifically involves the dismantling of trade barriers such as import licenses, quotas, and high tariffs that previously limited the participation of foreign entities in the domestic market.
  • In the context of the Indian economy, liberalization was a core component of the New Economic Policy (NEP) launched in 1991 to tackle a severe balance of payments crisis.
  • The process aimed to end the License Raj, allowing businesses to expand without bureaucratic hurdles and encouraging the flow of Foreign Direct Investment (FDI) and Foreign Institutional Investment (FII).
  • By facilitating the ease of doing business, liberalization helps in the efficient allocation of resources, improves industrial productivity, and ensures greater choice for consumers through global competition.

 Additional Information

  • Globalization:
  • Describes the process of rapid integration or interconnection between countries through the movement of goods, services, and people.
  • It is largely facilitated by advancements in information technology and transportation.
  • Protectionism:
  • An economic policy where governments use trade barriers like subsidies and restrictive quotas to shield domestic industries from foreign competition.
  • It is often used to nurture infant industries or protect national security interests.
  • Nationalization:
  • The process of transferring privately owned assets or industries into public ownership under the control of the national government.
  • A prominent example includes the nationalization of 14 major commercial banks in India in 1969.

View answer & explanation

Correct answer

Answer: (b)B.

Acts endangering the sovereignty, unity, and integrity of India.

Why this answer is correct

The correct answer is Acts endangering the sovereignty, unity, and integrity of India..

Key Points

  • Section 152 of the Bharatiya Nyaya Sanhita (BNS), 2023, specifically addresses offenses that threaten the sovereignty, unity, and integrity of India, effectively replacing the colonial-era Section 124A of the Indian Penal Code (IPC).
  • The provision penalizes any individual who, purposely or knowingly, by words (spoken or written), signs, visual representation, electronic communication, or the use of financial means, excites or attempts to excite secession, armed rebellion, or subversive activities.
  • It further covers acts that encourage feelings of separatist activities or any action that endangers the unity and integrity of the nation, shifting the legal focus from 'disaffection towards the government' to 'acts against the State'.
  • The punishment under Section 152 includes imprisonment for life or imprisonment for a term which may extend to seven years, along with a mandatory fine.
  • The Bharatiya Nyaya Sanhita was enacted to modernize Indian criminal law, and notably, the word sedition (Rajdroh) is not used in the new act; instead, it uses the framework of Deshdroh (acts against the nation).

 Additional Information

  • Comparison with Section 124A (IPC):
  • Scope: While Section 124A IPC focused on disaffection or hatred against the Government established by law, the BNS focuses on subversive activities and threats to the sovereignty of the Union of India.
  • Modernization: The BNS explicitly includes electronic communication as a medium for committing such offenses, reflecting the impact of digital and social media in contemporary national security concerns.
  • Terrorism: Unlike Section 152 which deals with sovereignty, Section 113 of the BNS specifically defines and penalizes Terrorist Acts for the first time in India's general criminal code.

View answer & explanation

Correct answer

Answer: (c)C.

A mix of financial, natural, human, and technological resources.

Why this answer is correct

The correct answer is A mix of financial, natural, human, and technological resources..

Key Points

  • Balanced Regional Development (BRD) is a multi-dimensional concept aimed at reducing economic and social disparities between different geographical regions of a country.
  • A holistic approach is required because reliance on a single factor like financial resources cannot yield sustainable growth; capital must be supported by skilled human labor and efficient technology to ensure productivity.
  • Natural resources act as the foundational base for a region's industrial or agricultural potential, defining its comparative advantage in sectors like mining in Jharkhand or agriculture in Punjab.
  • Human resources, developed through education and healthcare, are critical for local entrepreneurship and preventing the mass migration of talent to already developed metropolitan hubs.
  • Technological resources bridge the gap between rural and urban sectors by improving connectivity, enhancing industrial automation, and facilitating the digital delivery of services.
  • The integration of these four resources ensures that development is not just localized in tier-1 cities but reaches backward districts, fostering inclusive growth.

Question 766

Delhi Police Constable 2025• General Knowledge/Current Affairs

How many dynes are equivalent to 1 newton? 

  1. AOption (a)

    104dyne

  2. BOption (b)

    105dyne

  3. COption (c)

    10​6 dyne

  4. DOption (d)

    107 dyne

View answer & explanation

Correct answer

Answer: (b)B.

105dyne

Why this answer is correct

Concept:

  • The Newton is the SI unit (International System of Units) of force.
  • The Dyne is the CGS unit (Centimeter-Gram-Second) of force.
  • Force is defined as the product of mass and acceleration according to Newton's Second Law of Motion.
  • SI Unit: Newton (N) = 1 kg·m/s2.
  • Dimensional Formula: [M1L1T−2].
  • Important Formula: Force = Mass × Acceleration.

Calculation:

Force = 1 Newton (N)

1 kg = 103 g

1 m = 102 cm

1 Newton = 1 kg × 1 m/s2

⇒ 1 Newton = (103 g) × (102 cm/s2)

⇒ 1 Newton = (103 × 102) g·cm/s2

⇒ 1 Newton = 10(3+2) g·cm/s2

⇒ 1 Newton = 105 g·cm/s2

Since 1 dyne = 1 g·cm/s2:

⇒ 1 Newton = 105 dyne

Hence, 1 Newton is equivalent to 105 dyne. Therefore, the correct option is (2).

Read the following statements and choose the correct option.

Statement 1: The Western Ghats receive significant rainfall due to their proximity to the sea.

Statement 2: The Eastern Ghats receive more rainfall than the Western Ghats.

  1. AOption (a)

    Only Statement 1 is correct 

  2. BOption (b)

    Only Statement 2 is correct 

  3. COption (c)

    Both Statement 1 and Statement 2 are correct

  4. DOption (d)

    Neither Statement 1 nor Statement 2 is correct

View answer & explanation

Correct answer

Answer: (a)A.

Only Statement 1 is correct 

Why this answer is correct

The correct answer is Only Statement 1 is correct.

Key Points

  • The Western Ghats, also known as the Sahyadri, run parallel to the western coast of India and act as a massive barrier to the moisture-laden Southwest Monsoon winds originating from the Arabian Sea. Due to their elevation and proximity to the sea, these mountains force the winds to rise, resulting in heavy orographic rainfall on the windward side, often exceeding 250 cm annually. Hence, Statement 1 is correct.
  • The Eastern Ghats are significantly lower in elevation, discontinuous, and highly dissected by major peninsular rivers. They receive much less rainfall than the Western Ghats because they do not effectively obstruct the monsoon winds; most of their precipitation occurs during the Retreating Monsoon (October–November) rather than the main summer monsoon. Hence, Statement 2 is incorrect.

 Additional Information

  • Western Ghats:
  • They are recognized as a UNESCO World Heritage Site and one of the world’s eight hottest hotspots of biological diversity.
  • The range stretches approximately 1,600 km through the states of Gujarat, Maharashtra, Goa, Karnataka, Kerala, and Tamil Nadu.
  • The highest peak is Anamudi, located in Kerala.
  • Eastern Ghats:
  • They are an older mountain range compared to the Western Ghats and are composed of charnockites and khondalites.
  • Major rivers like the Godavari, Krishna, Mahanadi, and Kaveri drain into the Bay of Bengal by cutting through this range.
  • The average rainfall here ranges between 600 mm and 1,100 mm, which is significantly lower than the western counterpart.

  4. DOption (d)

    The goal post height is 2.54 meters

View answer & explanation

Correct answer

Answer: (c)C.

The goal post distance is 7.32 meters 

Why this answer is correct

The correct answer is The goal post distance is 7.32 m .

Key Points

  • According to the Laws of the Game established by the International Football Association Board (IFAB) and enforced by FIFA, the distance between the inner edges of the vertical goal posts is exactly 7.32 meters (which is equivalent to 8 yards). Hence, the statement regarding the goal post distance being 7.32 m is correct.
  • The height of the goal, measured from the ground to the lower edge of the horizontal crossbar, is standardized at 2.44 meters (equivalent to 8 feet). Hence, the statement that the goal post height is 2.14 m is incorrect.
  • The measurement of 8.32 meters for the distance between posts does not correspond to any standard FIFA regulation for adult professional football. Hence, the statement that the goal post distance is 8.32 m is incorrect.
  • Standard professional goal dimensions are fixed at a height of 2.44 meters, making the figure of 2.54 m inaccurate for official matches. Hence, the statement that the goal post height is 2.54 m is incorrect.

 Additional Information

  • Structural Specifications of Football Goals:
  • Post and Crossbar Width: Both the posts and the crossbar must have the same width and depth, which cannot exceed 12 centimeters (5 inches).
  • Line Alignment: The goal line must be the same width as the goal posts and crossbar to ensure clear Goal-Line Technology accuracy.
  • Safety Standards: Goals must be securely anchored to the ground; portable goals may only be used if they satisfy this safety requirement.
  • Color and Shape: Goal posts and crossbars must be white and can be square, rectangular, round, or elliptical in shape.
  • Netting: While not mandatory under the basic laws, nets are usually attached to the goals and the ground behind the goal, supported in a way that does not interfere with the goalkeeper.

  4. DOption (d)

    Government regulation of small-scale industries.

View answer & explanation

Correct answer

Answer: (b)B.

Industrial licensing for most sectors.

Why this answer is correct

The correct answer is Industrial licensing for most sectors..

Key Points

  • The New Industrial Policy, announced on July 24, 1991, aimed at dismantling the License Raj to foster a more competitive and efficient industrial environment.
  • A primary feature of this reform was the abolition of industrial licensing for all projects, regardless of investment levels, except for a short list of 18 industries related to security, strategic concerns, and social reasons.
  • Before 1991, entrepreneurs required government permission (licenses) to start, relocate, or even expand the production capacity of a factory; the removal of these hurdles allowed for market-driven growth.
  • Currently, the list of industries requiring compulsory licensing has been further pruned down to only five sectors, including aerospace and defense, industrial explosives, and hazardous chemicals.
  • The reform also significantly reduced the role of the public sector, decreasing the number of industries reserved for it from 17 to just a few strategic sectors like atomic energy and railway transport.

 Additional Information

  • Liberalization Measures:
  • MRTP Act: The Monopolies and Restrictive Trade Practices Act was amended to remove the threshold limit of assets, eliminating the need for large houses to seek prior approval for expansion or mergers.
  • Foreign Investment: The policy allowed for automatic approval of Foreign Direct Investment (FDI) up to 51% in high-priority industries, easing restrictions on foreign ownership.
  • Deregulation: Many goods that were previously reserved for Small-Scale Industries (SSI) were gradually dereserved to allow larger firms to produce them, enhancing economies of scale.
  • Price Controls: While the government moved away from price controls in many sectors, it did not remove them for 'all' prices; essentials like life-saving drugs and fertilizers often remain regulated.

  4. DOption (d)

    Multiplying the births by the deaths and migrations

View answer & explanation

Correct answer

Answer: (b)B.

Subtracting the earlier population from the later population.

Why this answer is correct

The correct answer is Subtracting the earlier population from the later population.

Key Points

  • The absolute increase in population is the actual number of people added to the total population during a specific timeframe, such as a decade.
  • To calculate this value, the population figure from an earlier census is subtracted from the population figure of a later census; for example, subtracting the 2001 population from the 2011 population gives the absolute increase for that decade.
  • This metric is fundamental in demography as it represents the net magnitude of increase in raw numbers, rather than a relative percentage or rate.
  • In the Indian Census, calculating the absolute increase is vital for the government to determine the scale of infrastructure, healthcare, and educational facilities required for the additional citizens.

 Additional Information

  • Population Density:
  • Defined as the number of persons residing per unit of area, typically measured per square kilometer.
  • It is calculated by dividing the total population by the total land area of a region.
  • Annual Growth Rate:
  • Refers to the pace of population increase expressed as a percentage per year.
  • A growth rate of 2 percent per annum means there is an increase of two persons for every 100 persons in the base population.
  • Components of Population Change:
  • Birth Rate: The number of live births per 1,000 persons in a single year.
  • Death Rate: The number of deaths per 1,000 persons in a single year.
  • Migration: The movement of people across territories, which can be internal (within the country) or international (between countries).

  1. AOption (a)

    Large hemispherical domes (stupas)

  2. BOption (b)

    Monumental stone temples

    Free-standing sculptures of Buddha

View answer & explanation

Correct answer

Answer: (c)C.

Monolithic pillars crowned with animal capitals

Why this answer is correct

The correct answer is Monolithic pillars crowned with animal capitals.

Key Points

  • The Ashokan Pillars are the most distinctive examples of Mauryan Court Art, representing the high point of stone masonry and aesthetic precision during the 3rd century BCE.
  • These structures are strictly monolithic, meaning the long, tapering shafts were carved from a single block of buff-colored Chunar sandstone quarried from Mirzapur.
  • The defining feature of these pillars is the Mauryan Polish, a unique, glass-like luster applied to the stone surface that remains a subject of scientific wonder due to its durability.
  • Each pillar typically features a lotus-shaped capital (bell-shaped), an abacus (a decorative circular or rectangular base), and a crowning animal sculpture like the lion, bull, or elephant.
  • The Lion Capital of Sarnath is the most famous example, featuring four back-to-back lions; it was adopted as the National Emblem of India on January 26, 1950.
  • These pillars were used as pillars of Dhamma, bearing inscriptions of Emperor Ashoka’s edicts to promote social harmony and Buddhist principles throughout the Mauryan Empire.

 Additional Information

  • Large hemispherical domes (stupas)
  • While Ashoka is credited with building thousands of Stupas, including the core of the Great Stupa at Sanchi, they are primarily reliquary mounds and not as uniquely exclusive to his architectural innovation as the monolithic pillars.
  • Monumental stone temples
  • The tradition of monumental free-standing stone temples only fully developed during the Gupta Period (4th−6th century CE), far after the Mauryan era.
  • Free-standing sculptures of Buddha
  • In the Mauryan period, Buddha was represented through symbols (like feet or the Bodhi tree). Anthropomorphic Buddha sculptures emerged later in the Gandhara and Mathura schools of art during the Kushan Empire.

Answer: (b)B.

Harrod-Domar Model

Why this answer is correct

The correct answer is Harrod-Domar Model.

Key Points

  • The First Five-Year Plan in India was launched for the duration of 1951 to 1956 by the government of Prime Minister Jawaharlal Nehru.
  • This plan was primarily based on the Harrod-Domar Model, which emphasizes that economic growth depends on the level of savings and the capital-output ratio.
  • The model posits that investment is the primary driver of growth; higher savings lead to higher investment, which increases the capital stock of the economy.
  • The plan was formulated at a time when the Indian economy was struggling with the aftermath of partition, food shortages, and inflation.
  • Consequently, the plan gave the highest priority to agriculture, irrigation, and power projects to ensure food security and rural development.
  • Major multipurpose projects like the Bhakra-Nangal Dam, Hirakud Dam, and Damodar Valley Corporation were initiated during this period.
  • The plan was a grand success as it achieved a growth rate of 3.6%, significantly exceeding the initial target of 2.1%.

 Additional Information

  • Harrod-Domar Model:
  • Developed by Roy F. Harrod (1939) and Evsey Domar (1946) to explain the relationship between growth and capital.
  • It identifies three types of growth: warranted growth, natural growth, and actual growth.
  • Solow-Swan Model:
  • An exogenous growth model that analyzes changes in the level of output based on population growth, savings, and technological progress.
  • Unlike Harrod-Domar, it assumes diminishing returns to labor and capital.
  • Keynesian Model:
  • Developed by John Maynard Keynes, it focuses on the role of aggregate demand and government intervention to manage economic cycles.
  • Mahalanobis Model:
  • Formulated by Prasanta Chandra Mahalanobis, this model served as the basis for the Second Five-Year Plan (1956-61).
  • It shifted the focus toward heavy industries and capital goods to achieve long-term industrial self-reliance.
