Bihar GK Questions 2026

Static GK is the largest part of General Studies in Bihar exams. The BPSC CCE Prelims asks General Science, the history of India with salient features of the history of Bihar, general geography with the geographical divisions and rivers of Bihar, Indian Polity and Economy with changes in Bihar's economy after independence, and the Indian National Movement with Bihar's part in it. The Mains goes deeper into Modern History, Indian culture, Polity, the Economy, Geography and science and technology. BSSC's General Studies covers India and its neighbours, the Constitution, panchayati raj and the freedom movement, and its General Science part is of matric level. This page holds GK24's topic-wise GK notes, written as short facts and tables so a topic can be revised in one sitting. They cover national GK: Polity, Ancient, Medieval and Modern History, Indian and world Geography, the Economy and General Science. GK24 does not have a separate Bihar GK section. As guidance, pair these notes with state sources, such as the Bihar Economic Survey and Bihar Board textbooks, for Bihar's history, geography, rivers and economy. Read a topic here, then solve its quiz and previous-year questions to check what stayed in memory.

Bihar GK Questions with Answers

  1. A.low coefficient of friction
  2. B.better heat dissipation
  3. C.smaller space consideration
  4. D.All of the above
Show answer
Correct answer: A. low coefficient of friction

Teflon is the trade name of polytetrafluoroethylene, a polymer whose surface is one of the most slippery among solids, with a coefficient of friction of about 0.04.

Q487.General ScienceAsked in: Bihar · 29th Jan 2017Medium

Which option is correct about the wheel of a car moving on the road?

  1. A.Rolling friction > Static friction > Kinetic friction
  2. B.Static friction > Kinetic friction > Rolling friction
  3. C.Static Friction > Rolling Friction > Kinetic Friction
  4. D.Rolling friction > Kinetic friction > Static friction
Show answer
Correct answer: B. Static friction > Kinetic friction > Rolling friction

For the same pair of surfaces the order of friction is always static, then kinetic, then rolling. Static friction is the largest because the surfaces interlock while at rest and that grip has to be broken to start motion.

Q488.General ScienceAsked in: Bihar · 13th September 2025Medium

The potential energy of a freely falling body continuously decreases.

  1. A.The principle of conservation of energy is not violated
  2. B.The principle of conservation of energy is violated
  3. C.Gravitational force is violated
  4. D.Gravitational force is not violated
Show answer
Correct answer: A. The principle of conservation of energy is not violated

As the body falls its height shrinks, so the potential energy m g h falls, but exactly that much energy reappears as kinetic energy, half m v squared, because the body speeds up.

Q489.General ScienceAsked in: Bihar · BPSC Assistant 2014 Official PaperEasy

Convert sound energy into electrical energy

  1. A.By microphone
  2. B.By loudspeaker
  3. C.By sonometer
  4. D.By earphone
Show answer
Correct answer: A. By microphone

A microphone is a transducer: sound waves strike a thin diaphragm, the diaphragm vibrates, and that mechanical vibration is turned into a varying electric signal.

Q490.General ScienceAsked in: Bihar · BPSC Assistant 2014 Official PaperEasy

Sun appears red at sunset because

  1. A.The sun has only red color
  2. B.Red color is scattered more than other colors
  3. C.Red color scatters less than other colors
  4. D.Our eyes are more sensitive to red
Show answer
Correct answer: C. Red color scatters less than other colors

At sunset the Sun is close to the horizon, so its light travels through a much thicker layer of atmosphere before it reaches the eye.

Q491.Environment & EcologyAsked in: Bihar · BPSC AE Paper 3 (General Studies) 2019 OEasy

'Fly-ash', a well-known pollutant is produced by

Q496.General ScienceAsked in: Bihar · Nov 2015 (Advt. 22/2014Hard

A cylinder of mass m rolls down an inclined plane from a height h above a horizontal level. If the velocity of the axis of the cylinder is v when it reaches the lower level, then

  1. A.v = gh
  2. B.v = mgh
  3. C.v = √(2gh)
  4. D.v < √(2gh)
Show answer
Correct answer: D. v < √(2gh)

A body that slides down a smooth slope turns all of its potential energy mgh into translational kinetic energy and reaches the bottom with a speed equal to the square root of 2gh.

Q497.General ScienceAsked in: Bihar · 25 Mar 2022Medium

If a wire is placed parallel to the lines of force in a magnetic field and a current flows in the wire, then

  1. A.the wire will experience a force in the direction of the magnetic field

  3. C.the wire will experience a force in the direction opposite to the field
  4. D.it will experience a force in the direction perpendicular to the lines of force
Show answer
Correct answer: B. the wire will not experience any force at all

The force on a current carrying conductor kept in a magnetic field is given by F equal to B I L sin theta, where theta is the angle between the direction of the current and the direction of the field.

Q500.General ScienceAsked in: Bihar · Nov 2015 (Advt. 22/2014Medium

The linear momentum of a system of rigid bodies will be conserved, if

  1. A.the system is in a gravitational field
  2. B.no external forces act on the system
  3. C.kinetic energy is conserved
  4. D.none of the above
Show answer
Correct answer: B. no external forces act on the system

The law of conservation of linear momentum follows straight from Newton's second law: the rate of change of the momentum of a system equals the net external force acting on it, so when that force is zero the total momentum stays the same in size and in direction.
