CDS GK Questions 2026

Static GK carries most of the 100 marks of the CDS General Knowledge paper. Of the 120 questions in the CDS (II) 2026 paper, about 20 were on Indian Polity, about 20 on the History of India, about 15 on Geography and the environment, about 10 on the Indian Economy and about 37 on Physics, Chemistry and Biology, which makes CDS the most science-heavy General Knowledge paper among the major recruitment exams. Polity questions test writs, the NHRC, electoral systems, disqualification of legislators, GST and delimitation. History runs from the Upanishads and the Shunga dynasty to Vijayanagara, temple architecture, the Sylhet referendum and the SNDP Yogam. Geography asks about the atmosphere, earthquakes and tsunamis, Ramsar sites, mangroves and World Heritage sites. Science stays at school level but expects reasoning: a lens problem, a magnetic field direction, molarity versus molality, what cooking soda is, how enzymes act. This page holds GK24's topic-wise GK notes for CDS, written as short facts and tables so that 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 stayed with you.

CDS GK Questions with Answers

Q4341.General ScienceAsked in: NDA · NDA-I 2021, GATEasy

The statement "friction force is a contact force while magnetic force is a non-contact force" is

  1. A.always true.
  2. B.true only at 0°C.
  3. C.a false statement.
  4. D.either true or false depending upon the temperature of the surroundings.
Show answer
Correct answer: A. always true.

Friction acts only where two surfaces touch, while a magnet can push or pull an object across a gap. Forces are grouped by whether the bodies must touch.

Q4349.General ScienceAsked in: NDA · NDA-I 2026, GATMedium

For an object in gravitational field, the gravitational potential is the same at two points A and B, but the gravitational field is not the same at these two points. Which one of the following statements is correct?

  1. A.Positive work is done by gravity in moving the object from point A to point B.
  2. B.Negative work is done by gravity in moving the object from point A to point B.
  3. C.Gravity must be non-conservative in such a region.
  4. D.No work is done by gravity in moving the object from point A to point B.
Show answer
Correct answer: D. No work is done by gravity in moving the object from point A to point B.

Work done by gravity depends only on the difference in potential between the two points, and here that difference is zero.

Q4350.General ScienceAsked in: NDA · NDA-II 2026, GATHard

Consider the following : I. Gravitational field due to a spherical body II. Electrostatic field due to a point charge III. Strong nuclear force field due to a proton IV. Magnetic field due to a bar magnet How many of the above follow the inverse square law ?

  1. A.One
  2. B.Two
  3. C.Three
  4. D.All four
Show answer
Correct answer: B. Two

Only the gravitational field of a spherical body and the electrostatic field of a point charge fall off as 1/r².

Q4351.General ScienceAsked in: UPSC CAPF · CAPF 2019, Paper IEasy

Which of the following are the most favourable conditions for liquefying a gas ?

  1. A.Low pressure and high temperature
  2. B.Low pressure and low temperature
  3. C.High pressure and high temperature
  4. D.High pressure and low temperature
Show answer
Correct answer: D. High pressure and low temperature

High pressure pushes the gas molecules close together and low temperature slows them down, so the attractive forces can hold them as a liquid.

Q4352.General ScienceAsked in: UPSC CAPF · CAPF 2021, Paper IEasy

Which one among the following is not a luminous object?

  1. A.Sun
  2. B.Proxima Centauri
  3. C.Jupiter
  4. D.Alpha Centauri
Show answer
Correct answer: C. Jupiter

Jupiter is a planet; it does not make its own light and shines only by reflecting sunlight. A luminous object produces light of its own, as stars do by nuclear fusion in their cores, where hydrogen is turned into helium.

Q4354.General ScienceAsked in: UPSC CAPF · CAPF 2024, Paper IMedium

Which one among the following biotechnologies is applied to manufacture pharmaceutical products such as insulin, antibiotics and vaccines?

  1. A.White Biotechnology
  2. B.Red Biotechnology
  3. C.Green Biotechnology
  4. D.Blue Biotechnology
Show answer
Correct answer: B. Red Biotechnology

Red biotechnology is the branch applied to medicine and health care, including the making of insulin, antibiotics and vaccines. Biotechnology is often divided by colour according to its field of use.
