RRB NTPC GK Questions 2026

Static General Knowledge makes up the rest of the General Awareness section in RRB NTPC, and the notices name its topics: General Science and Life Science up to Class 10, History of India and the freedom struggle, Physical, Social and Economic Geography of India and the world, Indian Polity and Governance, Indian Economy, Art and Culture, Indian Literature, Monuments and Places, Flora and Fauna, Famous Personalities, the UN and other world organisations, environmental issues, Transport Systems in India, Important Government and Public Sector Organisations, Common Abbreviations, and Basics of Computers and Computer Applications. RRB frames these as short factual questions: the unit of a physical quantity, the year of a battle, the article of the Constitution, the river a city stands on, the full form of an abbreviation, the headquarters of an organisation. GK24's GK notes on this page cover each topic in English and Hindi, arranged the way the syllabus lists them, with the facts RRB tends to ask placed first. Work through one topic at a time, note the lists (national parks, dances, articles, schedules, awards), and pair each topic with its quiz on GK24 to check what has stayed with you.

RRB NTPC GK Questions with Answers

Q2201.General ScienceAsked in: Delhi · 27 June 2022, Shift 2Hard

The following statements (S1 and S2) pertain to principle of moments stated as Varignon theorem: S1: Theorem states that the Square of the moment of a Force is equal to the Sum of the Square moment of its components. S2: For applying Varignon Theorem, the force system may be either coplanar or spatial, but it must be concurrent. Identify the statements as True or False and choose the best answer.

  1. A.Both S1 and S2 are False
  2. B.Both S1 and S2 are True
  3. C.S1 is True and S 2 is False
  4. D.S1 is False and S 2 is True
Show answer
Correct answer: D. S1 is False and S 2 is True

Varignon theorem states that the moment of a force about any point equals the algebraic sum of the moments of its components about the same point; it speaks of the moments themselves, not of their squares, so statement S1 is false as written.

Q2202.General ScienceMedium

A spinning skater pulls both arms close to the body and spins faster. This happens because

  1. A.The angular momentum of the skater increases
  2. B.The moment of inertia decreases, so the angular velocity increases
  3. C.The torque applied by the skater increases
  4. D.The mass of the skater decreases
Show answer
Correct answer: B. The moment of inertia decreases, so the angular velocity increases

Moment of inertia is the sum of each bit of mass multiplied by the square of its distance from the axis, so drawing the arms in reduces it.

Q2203.General ScienceHard

The centre of gravity of a uniform solid right circular cone of height h lies on its axis at a distance of

  1. A.h divided by 2 from the base
  2. B.h divided by 3 from the base
  3. C.h divided by 4 from the base
  4. D.3h divided by 4 from the base
Show answer
Correct answer: C. h divided by 4 from the base

A solid cone has more material near its wide base than near its apex, so its centre of gravity lies on the axis of symmetry well below the middle, at one quarter of the height measured from the base, which is three quarters of the height measured down from the…

Q2204.General ScienceMedium

A wheelbarrow is an example of which class of lever?

  1. A.First class
  2. B.Second class
  3. C.Third class
  4. D.It is not a lever
Show answer
Correct answer: B. Second class

In a wheelbarrow the wheel is the fulcrum, the load in the tray lies between the wheel and the hands, and the effort is applied at the handles, so the load sits in the middle, which defines a second class lever; a nutcracker, a bottle opener and a lemon squeezer…

Q2205.General ScienceMedium

When a body in stable equilibrium is slightly displaced, its centre of gravity

  1. A.Rises, and the body returns to its original position
  2. B.Falls, and the body moves further away
  3. C.Stays at the same height
  4. D.Shifts outside the body
Show answer
Correct answer: A. Rises, and the body returns to its original position

In stable equilibrium the original position is the one of least potential energy, so a small displacement lifts the centre of gravity and the weight of the body brings it back, as with a cone resting on its base or a book lying flat on a table.

Q2206.General ScienceMedium

A rigid body is said to be in complete mechanical equilibrium when

  1. A.The net force on it is zero
  2. B.The net torque on it is zero
  3. C.Both the net force and the net torque on it are zero
  4. D.Its centre of gravity lies at its geometrical centre
Show answer
Correct answer: C. Both the net force and the net torque on it are zero

A zero net force gives translational equilibrium, so the body as a whole does not accelerate, and a zero net torque gives rotational equilibrium, so it does not begin to spin; complete equilibrium requires the two together.

Q2207.General ScienceEasy

A long spanner loosens a tight nut more easily than a short one because it

  1. A.Reduces the force needed by increasing the moment arm
  2. B.Reduces the friction at the nut
  3. C.Increases the mass acting on the nut
  4. D.Changes the direction of the weight of the nut
Show answer
Correct answer: A. Reduces the force needed by increasing the moment arm

Torque is the product of the force and the perpendicular distance of its line of action from the axis, so the same turning effect can be produced by a smaller force if that distance is made larger; a long handle therefore does the same work with less effort.

Q2209.General ScienceEasy

The centre of gravity of a uniform circular ring lies

  1. A.On the ring itself, at any point
  2. B.At the centre of the ring, outside its material
  3. C.At one third of the radius from the centre
  4. D.Nowhere, because a ring has no centre of gravity
Show answer
Correct answer: B. At the centre of the ring, outside its material

The centre of gravity is a geometrical point through which the resultant weight of a body acts, and by symmetry that point for a uniform ring is its geometrical centre, which lies in the empty space inside the ring.

Q2210.General ScienceAsked in: RRB JE · 29 Aug 2019Hard

Three forces acting on a rigid body are represented in magnitude, direction and line of action by the three sides of a triangle taken in order. The forces are equivalent to a couple whose moment is equal to

  1. A.Thrice the area of the triangle
  2. B.Twice the area of the triangle
  3. C.The area of the triangle
  4. D.Half the area of the triangle
Show answer
Correct answer: B. Twice the area of the triangle

When three forces are represented by the sides of a triangle taken in order, their vector sum is zero, because the three sides close the triangle, so the body cannot be pushed away; but the lines of action are different, so the system reduces to a couple.

Q2211.General ScienceEasy

What is the SI unit of torque?

  1. A.Newton
  2. B.Newton metre
  3. C.Newton per metre
  4. D.Joule per second
Show answer
Correct answer: B. Newton metre

Torque is the product of a force and the perpendicular distance of its line of action from the axis of rotation, so its unit is the unit of force multiplied by the unit of length, the newton metre, and its dimensional formula is M L squared T to the power…
