Defence GK Questions 2026

Magadha was the first power of ancient India to use elephants in war on a large scale, taking them from the forests of its east Indian heartland.

The Inter-Parliamentary Union is the global body of national parliaments and runs its own affairs, so an election at the United Nations is not on its programme.

He is to sit in the Governing Council of the Inter-Parliamentary Union, speak in the General Debate and in the debate on the emergency item, and attend the hearing of those who are candidates for the post of IPU President.

The Assembly and the meetings held around it are taking place at Arusha, a city in that country, from 5 to 9 October 2026, and the Indian Parliamentary Delegation left for Arusha for this purpose.

Potassium permanganate is a neutral compound, so the oxidation numbers of all its atoms must add up to zero. Potassium, an alkali metal, is always +1, and each of the four oxygen atoms is -2, giving the oxygens a total of -8.

Coulomb friction, also called dry friction, is the resistance that acts when two solid surfaces touch each other with no lubricant between them.

A concave lens, also called a diverging lens, spreads out the rays that fall on it and so can never bring them to a real focus.

Wetting is decided by a contest between two forces: cohesion, the attraction among the molecules of the liquid itself, and adhesion, the attraction between the liquid and the solid surface.

The atomic number of an element is by definition the number of protons in its nucleus, so an atomic number of 11 means 11 protons.

The four thematic areas, each with its own hub, are quantum computing at the Indian Institute of Science Bengaluru, quantum communication at the Indian Institute of Technology Madras, quantum sensing and metrology at the Indian Institute of Technology Bombay, and quantum materials and devices at the Indian Institute of Technology…

Micius was launched in 2016 and was used to demonstrate quantum key distribution between a satellite and ground stations, and entanglement distribution over distances far greater than optical fibre allows, since fibre loses photons rapidly over long runs.

Charles Bennett and Gilles Brassard proposed the protocol in that year, and the name BB84 combines their initials with the year.

The Union Cabinet approved this amount on 19 April 2023 for the period 2023-24 to 2030-31, that is an eight year span, and the Department of Science and Technology implements the mission within it.

The no cloning theorem forbids an exact copy of an unknown state, and any measurement changes the state, so an eavesdropper on the channel inevitably leaves statistical traces that the two legitimate parties detect when they compare a sample of their key.

Peter Shor published the algorithm in 1994, and it would let a sufficiently large quantum computer break the large number factorisation on which public key encryption such as the RSA system depends.

A classical bit must be either zero or one, but a qubit can occupy a combination of both states until it is measured, and this is what allows a register of n qubits to represent two raised to the power n states together.

The mission divides the field among four thematic hubs, and quantum computing was assigned to the Indian Institute of Science.

This is the headline target stated when the Cabinet approved the mission, and it is to be achieved on more than one hardware platform, including superconducting and photonic technology, rather than on a single design.

The Union Cabinet approved the mission on 19 April 2023 and placed its implementation with that department, which runs it through four thematic hubs at leading academic institutions.

In the Gupta age a workshop at Sarnath, near Varanasi, carved in cream Chunar sandstone and produced the seated preaching Buddha whose hands form the dharmachakra mudra, the gesture of teaching, and whose robe clings so closely that art historians describe it as wet drapery.
