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

Q5642.General ScienceAsked in: NDA · NDA-II 2017, GATMedium

An object moves in a circular path with a constant speed. Which one of the following statements is correct ?

  1. A.The centripetal acceleration of the object is smaller for a gentle curve (i.e., curve of larger radius) than that for a sharp curve (i.e., curve of smaller radius).
  2. B.The centripetal acceleration is greater for a gentle curve than that for a sharp curve.
  3. C.The centripetal acceleration is the same for both, the gentle and sharp curves.
  4. D.The centripetal acceleration causes the object to slow down.
Show answer
Correct answer: A. The centripetal acceleration of the object is smaller for a gentle curve (i.e., curve of larger radius) than that for a sharp curve (i.e., curve of smaller radius).

At a fixed speed v, centripetal acceleration equals v²/r, so a larger radius gives a smaller acceleration. An object moving in a circle at constant speed is still accelerating, because its direction keeps changing.

Q5643.General ScienceAsked in: NDA · NDA-II 2018, GATEasy

Which one of the following depicts the correct circuit of a reflex arc?

  1. A.Effector—sensory neuron—spinal cord—motor neuron—receptor
  2. B.Receptor—sensory neuron—spinal cord—motor neuron—effector
  3. C.Receptor—sensory neuron—brain—motor neuron—effector
  4. D.Sensory neuron—receptor—brain—effector—motor neuron
Show answer
Correct answer: B. Receptor—sensory neuron—spinal cord—motor neuron—effector

In a reflex arc the message runs from the sense organ to the spinal cord and straight back to a muscle or gland.

Q5644.General ScienceAsked in: NDA · NDA-I 2019, GATEasy

Basic scientific principle behind a nuclear reactor is

  1. A.Nuclear fusion
  2. B.Controlled nuclear fusion
  3. C.Uncontrolled nuclear fission
  4. D.Controlled nuclear fission
Show answer
Correct answer: D. Controlled nuclear fission

A nuclear reactor splits heavy nuclei such as uranium-235 in a chain reaction that is kept under control, releasing heat at a steady rate.

Q5645.General ScienceAsked in: NDA · NDA-II 2019, GATMedium

Mitochondria are able to produce their own

  1. A.Nucleus
  2. B.Proteins
  3. C.Chloroplasts
  4. D.Digestive enzymes
Show answer
Correct answer: B. Proteins

Mitochondria have their own DNA and their own ribosomes, so they can make some of the proteins they need. Mitochondria are the "powerhouses of the cell", where food is broken down in aerobic respiration to release energy stored as ATP.

Q5650.General ScienceAsked in: NDA · NDA-II 2023, GATEasy

Ms. Rani decides to convert her AC generator into a DC generator. Which one of the following she would need to use ?

  1. A.A split-ring type commutator
  2. B.Slip rings and brushes
  3. C.A stronger magnetic field
  4. D.A rectangular wire loop
Show answer
Correct answer: A. A split-ring type commutator

A split-ring commutator reverses the coil's connection to the outer circuit every half turn, so the current outside flows in one direction only.

Q5653.Indian HistoryAsked in: NDA · NDA-II 2025, GATMedium

In the Harappan Civilization, traces of canals have been found at

  1. A.Banawali
  2. B.Lothal
  3. C.Shortughai
  4. D.Dholavira
Show answer
Correct answer: C. Shortughai

Shortughai, a Harappan trading settlement in north-eastern Afghanistan, is the site where traces of irrigation canals have been found. Most Harappan farmers relied on river floods and wells, and no canals have been found in the Indus heartland.

Q5654.General ScienceAsked in: NDA · NDA-II 2026, GATMedium

Consider the following statements : I. A solution of iodine in ethanol known as 'tincture of iodine' is a heterogeneous mixture. II. A suspension is a heterogeneous mixture and its particles scatter a beam of light passing through it, making its path visible. III. A colloidal solution, although it appears homogeneous, is a heterogeneous mixture. Which of the statements given above are correct ?

  1. A.I and II only
  2. B.II and III only
  3. C.I and III only
  4. D.I, II and III
Show answer
Correct answer: B. II and III only

Tincture of iodine is a true solution, which is homogeneous, so statement I is wrong, while II and III are right.

The intelligence that set off the operation said the truck carrying ganja from Nepal would come into Uttar Pradesh through Sonauli, so officers of the Directorate of Revenue Intelligence at Gorakhpur built their surveillance around that crossing, helped by teams at Lucknow, Patna and Varanasi.
