SSC CGL GK Questions 2026

Static GK decides the General Awareness score in SSC CGL. Of the 25 questions in Tier-I and the 25 in Tier-II Paper-I, most come from Indian Polity, History, Geography, the Economy and General Science, the areas the CGL 2026 notice lists as History, Culture, Geography, Economic Scene, General Policy and Scientific Research relating to India and its neighbouring countries. Polity questions ask about articles, parts and schedules of the Constitution, amendments, the President, Parliament, the Supreme Court and constitutional bodies. History covers the Indus Valley, the Mauryas and Guptas, the Delhi Sultanate and Mughals, and the freedom struggle from 1857 to 1947. Geography asks about rivers, soils, climate, national parks, minerals and world physical features. The Economy part asks about budget terms, the RBI, banking and basic concepts. General Science is school-level Physics, Chemistry and Biology. This page holds GK24's topic-wise GK notes for SSC CGL, written as short facts and tables so a topic can be revised in one sitting. Read a topic, then solve its previous-year questions and quiz on this site to check what you retained.

SSC CGL GK Questions with Answers

Q11544.General ScienceMedium

Which was the first nuclear power station to be set up in India?

  1. A.Tarapur, Maharashtra
  2. B.Kalpakkam, Tamil Nadu
  3. C.Rawatbhata, Rajasthan
  4. D.Narora, Uttar Pradesh
Show answer
Correct answer: A. Tarapur, Maharashtra

The Tarapur Atomic Power Station was the first nuclear power station in India and also the first in Asia, built with American collaboration and using boiling water reactors, unlike the pressurised heavy water reactors of the later Indian stations.

Q11546.General ScienceEasy

The energy radiated by the Sun is produced mainly by which process?

  1. A.Nuclear fission of uranium
  2. B.Nuclear fusion of hydrogen nuclei
  3. C.Chemical combustion of hydrogen
  4. D.Radioactive decay of heavy elements
Show answer
Correct answer: B. Nuclear fusion of hydrogen nuclei

In the core of the Sun, at temperatures of millions of degrees, hydrogen nuclei fuse in stages to form helium, and the small amount of mass lost in the process appears as energy according to Einstein's mass-energy relation.

Q11547.General ScienceMedium

Control rods used to regulate the rate of a nuclear chain reaction are commonly made of which materials?

  1. A.Graphite and heavy water
  2. B.Cadmium and boron
  3. C.Lead and concrete
  4. D.Uranium and plutonium
Show answer
Correct answer: B. Cadmium and boron

Both absorb neutrons strongly, so pushing the rods into the core removes neutrons and slows the chain reaction, while withdrawing them allows the reaction to build up; this is how the power of a reactor is controlled and how it is shut down.

Q11548.General ScienceMedium

In a nuclear reactor, heavy water is used mainly for which purpose?

  1. A.As a moderator
  2. B.As a fuel
  3. C.As a control rod
  4. D.As shielding
Show answer
Correct answer: A. As a moderator

Heavy water, in which the hydrogen of ordinary water is replaced by deuterium, slows the fast neutrons released in fission to low speeds at which they are far more likely to split further uranium nuclei, and it absorbs very few neutrons in doing so, which is why Indian pressurised heavy…

Q11550.General ScienceMedium

When a nucleus emits an alpha particle, how do its mass number and atomic number change?

  1. A.Mass number falls by 2 and atomic number by 1
  2. B.Mass number falls by 4 and atomic number by 2
  3. C.Mass number is unchanged and atomic number rises by 1
  4. D.Both remain unchanged
Show answer
Correct answer: B. Mass number falls by 4 and atomic number by 2

An alpha particle takes away two protons and two neutrons, so the parent loses four units of mass number and two units of atomic number and becomes an element two places earlier in the periodic table; uranium-238, for instance, becomes thorium-234.

Q11552.General ScienceEasy

Radioactivity was discovered by which scientist?

  1. A.Henri Becquerel
  2. B.Marie Curie
  3. C.Ernest Rutherford
  4. D.Wilhelm Roentgen
Show answer
Correct answer: A. Henri Becquerel

In 1896 Becquerel found that a uranium salt kept in the dark fogged a wrapped photographic plate, which showed that the salt emitted its own penetrating radiation without being exposed to light.

Q11553.General ScienceAsked in: Bihar · BPSC AE Paper 3, 2019Medium

A hydrogen bomb creates devastating explosion because of

  1. A.nuclear fission and nuclear fusion
  2. B.nuclear fission
  3. C.the use of the cryogenic hydrogen
  4. D.the use of ultra pressed hydrogen
Show answer
Correct answer: A. nuclear fission and nuclear fusion

A hydrogen bomb, also called a thermonuclear bomb, works in two steps. A fission explosion of uranium or plutonium produces the temperature of millions of degrees needed to force light nuclei together, and the fusion of those nuclei then releases far more energy than the fission stage alone.

Q11556.EconomyMedium

What equity stake does JSW Projects currently hold in BMM Ispat Limited?

  1. A.26.00 per cent
  2. B.51.00 per cent
  3. C.58.47 per cent
  4. D.74.90 per cent
Show answer
Correct answer: C. 58.47 per cent

JSW Projects Limited, an unlisted company of the JSW Group based in Mumbai, holds that share of the equity in BMM Ispat Limited at present, and the proposed combination is meant to convert this majority interest into full ownership by amalgamating BMM into JSW Steel Limited.

Q11557.EconomyEasy

Which regulator approved the proposed combination amalgamating BMM Ispat into JSW Steel?

  1. A.Securities and Exchange Board of India
  2. B.Competition Commission of India
  3. C.Reserve Bank of India
  4. D.Insolvency and Bankruptcy Board of India
Show answer
Correct answer: B. Competition Commission of India

It is the statutory authority that examines proposed combinations, meaning mergers, amalgamations and acquisitions above the prescribed thresholds, to see whether they would cause an appreciable adverse effect on competition in India, and it cleared this internal restructuring of the JSW Group along with three other combinations the same day.

Q11558.Banking & FinanceMedium

By when must the bankers committees submit their action-taken report to the Department of Financial Services?

  3. C.24 September 2026
  4. D.30 October 2026

  2. B.Article 330
  3. C.Article 341
  4. D.Article 342
