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.

Isobars of elements have same :

  1. A.Atomic numbers.
  2. B.Number of electrons.
  3. C.Mass numbers.
  4. D.Number of neutrons.
Show answer
Correct answer: C. Mass numbers.

Isobars are atoms of different elements that have the same mass number but different atomic numbers. The mass number is the total of protons and neutrons in the nucleus, so isobars have the same number of nucleons arranged differently: more protons and fewer neutrons in one, the reverse in another.

Q2184.General ScienceAsked in: CDS · CDS-II 2026, GKMedium

Three resistors, R1, R2 and R3, (R1 > R2 > R3), are connected to a battery of voltage V, such that the circuit generates maximum heat per unit time. Which one among the following is the correct circuit combination for this ?

  1. A.R1, R2 and R3 are connected in series combination
  2. B.R1, R2 and R3 are connected in parallel combination
  3. C.R1 and R3 are connected in parallel and R2 is connected in series to the combination
  4. D.R1 and R3 are connected in series and R2 is connected parallel to the combination
Show answer
Correct answer: B. R1, R2 and R3 are connected in parallel combination

Heat produced per unit time is the power, and with a fixed battery voltage the power is P = V²/R. So the circuit gives the most heat when its total resistance is the smallest, and the smallest possible resistance comes from joining all three resistors in parallel.
