Defence GK Questions 2026

Static GK carries most of the General Knowledge marks in the defence exams, and science carries the largest share of it. In NDA & NA, Physics, Chemistry and General Science are about half of the 400 marks of Part B, and History, the freedom movement and Geography are about 20% each, as per the notice. In the CDS (II) 2026 General Knowledge paper, GK24 counted about 37 science questions, about 20 each on Polity and History, about 15 on Geography and environment and about 10 on the Economy; this count is guidance, not an official break-up. The Army's Agniveer CEE gives 15 of its 50 General Duty questions to General Knowledge and 15 to General Science, which covers cells, the human body, plants and animals and common epidemics. Its GK list names history, culture and geography of India and its neighbours, the Constitution, inventions and discoveries, books and authors, and the Indian Armed Forces. This page holds GK24's topic-wise GK notes and GK questions tagged for NDA, CDS and Agniveer, in English and Hindi: General Science, Indian History, Art and Culture, Indian Polity, Geography, Indian Economy and Static GK. Read one topic at a sitting, then solve its questions and the previous-year questions of your exam to see what stayed with you.

Q3673.General ScienceAsked in: UPSC CAPF · CAPF 2023, Paper IMedium

In experiment #1, a bar magnet is moved towards a conducting wire loop axially, with the magnet's north pole facing the loop. In experiment #2, the same process as in experiment #1 is repeated except that the south pole of the magnet faces the loop. Which one of the following statements is true in this context?

  1. A.The direction of current in the loop will be of opposite nature in both the experiments.
  2. B.The direction of current in the loop will be the same in both the experiments.
  3. C.No current will flow in either of the two experiments.
  4. D.More current will flow in the loop in experiment #1.
Show answer
Correct answer: A. The direction of current in the loop will be of opposite nature in both the experiments.

Reversing the pole that approaches the loop reverses the change in magnetic flux, so the induced current reverses too. When a magnet moves towards a closed loop, the magnetic flux through the loop changes and an electric current is induced (Faraday's law of electromagnetic induction).

Q3675.GeographyAsked in: UPSC CAPF · CAPF 2025, Paper IMedium

Which of the following statements is/are correct?

1. The time at 180° longitude is exactly 12 hours from the 0° longitude, irrespective of whether one travels westward or eastward from the Prime Meridian.

2. A person moving eastward on Tuesday will count the day as Wednesday once the International Date Line is crossed.

Select the answer using the code given below.

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2
Show answer
Correct answer: A. 1 only

Statement 1 is right, but statement 2 has the date change the wrong way round. The Earth turns 360° in 24 hours, so every 15° of longitude means one hour of time.
