UPSC CAPF GK Questions 2026

Static general knowledge fills most of Paper-I in UPSC CAPF. Of the six areas the CAPF (ACs) 2026 notice lists for General Ability and Intelligence, four are static: General Science; Indian Polity and Economy; History of India; and Indian and World Geography. The notice's wording shows the depth expected. Polity covers the political system and the Constitution of India, social systems, public administration, security issues and human rights with their indicators. Economy covers economic development in India. History covers social, economic and political aspects, including the growth of nationalism and the freedom movement. Geography covers physical, social and economic aspects of India and the world. General Science asks about everyday scientific phenomena and new areas such as Information Technology, Biotechnology and Environmental Science. This page holds GK24's topic-wise GK notes for UPSC CAPF, in English and Hindi, written as short facts and tables so that a topic can be revised in one sitting: Indian Polity, Indian History, Geography, Indian Economy, General Science, Environment and Ecology, Computer, and Art and Culture. The same notes serve Paper-II, whose essay part suggests modern Indian history, the freedom struggle, geography, polity and economy as topics. Read one topic at a time, then solve its quiz and the CAPF previous-year questions on this site to check what you have retained. General Mental Ability, the sixth area, is reasoning and arithmetic, and needs separate practice.

  1. A.Nitrogen
  2. B.Phosphate only
  3. C.Potassium only

  1. A.Burning of coal
  2. B.Burning of wood
  3. C.Heating of a platinum crucible
  4. D.Heating of potassium chlorate
Show answer
Correct answer: C. Heating of a platinum crucible

Platinum only gets hot and may glow; it does not react, and on cooling the crucible is exactly as it was, so the change is physical.

Show answer
Correct answer: C. The President may resign before the expiration of his/her term by writing to the Speaker of the Lok Sabha.

Under Article 56, the President resigns by writing to the Vice-President of India, not to the Speaker of the Lok Sabha, so this statement is not correct.

Q1870.General ScienceAsked in: CDS · CDS-II 2021, GKEasy

Rupa and Sachin observed an animal in their school garden. Rupa called it an insect while Sachin identified it as an earthworm. Which one of the following characteristics confirms that it is an insect ?

  1. A.The animal had jointed legs.
  2. B.Body of the animal had very little segmentation.
  3. C.Body of the animal was cylindrical.
  4. D.Body of the animal was bilaterally symmetrical.
Show answer
Correct answer: A. The animal had jointed legs.

Jointed legs are the mark of the phylum Arthropoda, to which insects belong; an earthworm has no legs at all.

Q1871.Environment & EcologyAsked in: CDS · CDS-I 2022, GKEasy

Which one of the following is the main reason of acid rains ?

  1. A.Dissolution of sulphur and nitrogen oxides in rain
  2. B.Dissolution of minerals in rain
  3. C.Dissolution of dust particles in rain
  4. D.Dissolution of soil solution in rain
Show answer
Correct answer: A. Dissolution of sulphur and nitrogen oxides in rain

These gases react with water in the air to form sulphuric and nitric acids, which fall as acid rain. Sulphur dioxide comes mainly from burning coal and oil in power plants and smelters, and nitrogen oxides from vehicle engines and high-temperature furnaces.

Q1872.General ScienceAsked in: CDS · CDS-II 2022, GKMedium

A metal wire of length l and diameter d has a resistance R. What would be the resistance of another wire of the same metal and of same length but having double the diameter ?

  1. A.R
  2. B.R/4
  3. C.R/2
  4. D.2R
Show answer
Correct answer: B. R/4

Resistance varies inversely with the area of cross-section, and doubling the diameter makes the area four times larger. The resistance of a wire is R = ρl/A, where ρ is the resistivity of the metal, l the length and A the cross-sectional area.

Q1874.Environment & EcologyAsked in: CDS · CDS-I 2024, GKEasy

The use of plastics has led to a number of environment-related problems. For this, which one of the following statements is correct?

  3. C.They do not have any biochemical synthesis activity.
  4. D.They are harmless to humans.
Show answer

Bacteria and fungi cannot break down most plastics, so plastic waste stays in soil and water for hundreds of years.

Q1876.General ScienceAsked in: CDS · CDS-II 2025, GKEasy

Which one among the following is the correct scheme followed for classification of animals ?

  1. A.Class → Phylum → Order → Genus → Family → Species

  4. D.Phylum → Class → Order → Family → Genus → Species
Show answer
Correct answer: D. Phylum → Class → Order → Family → Genus → Species

This is the taxonomic hierarchy for animals, going from the broadest group down to the most specific. Linnaeus built this ladder of ranks, and each rank contains one or more ranks below it.
