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.

Q1998.Science & TechnologyHard

According to the ARIES study, what happens to the shock in the accretion disc when a black hole spins rapidly?

  1. A.It is pushed farther from the black hole, giving only low-frequency QPOs
  2. B.It is pulled closer to the black hole, producing QPOs over a wider range of frequencies
  3. C.It disappears completely and no QPOs are produced
  4. D.It becomes permanently stable and stops oscillating
Show answer
Correct answer: B. It is pulled closer to the black hole, producing QPOs over a wider range of frequencies

The simulations showed that as spin increases, the oscillating shock moves inward and its oscillations grow more pronounced, so the predicted frequencies can exceed 100 Hz for a black hole of about ten solar masses, which matches the fast variations observed in black hole X-ray binary systems.

Q1999.Science & TechnologyEasy

In the context of black hole research, QPO stands for:

  1. A.Quantum Photon Oscillation
  2. B.Quasi-Periodic Oscillation
  3. C.Quadrupole Phase Orbit
  4. D.Quasar Polar Outflow
Show answer
Correct answer: B. Quasi-Periodic Oscillation

Matter pulled towards a black hole forms an accretion flow that falls inward at high speed and emits non-thermal radiation, and the brightness of that radiation shows nearly regular variations known as quasi-periodic oscillations.

Q2000.Science & TechnologyMedium

The study on the effect of black hole spin on quasi-periodic oscillations was led by scientists of which institute?

  1. A.Indian Institute of Astrophysics, Bengaluru
  2. B.Aryabhatta Research Institute of Observational Sciences (ARIES)
  3. C.Physical Research Laboratory, Ahmedabad
  4. D.Inter-University Centre for Astronomy and Astrophysics, Pune
Show answer
Correct answer: B. Aryabhatta Research Institute of Observational Sciences (ARIES)

Its Numerical and Theoretical Astrophysics Group built the computer simulation of viscous accretion flows used in the work, which was led by Mr Sanit Debnath and Dr Indranil Chattopadhyay, with scientists from the Nicolaus Copernicus Astronomical Center in Poland and MJP Rohilkhand University, Bareilly.
