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

Q3564.GeographyMedium

Out of 100 units of insolation received at the top of the atmosphere, how many units are reflected back to space, a share called the albedo of the earth?

  1. A.14 units
  2. B.17 units
  3. C.35 units
  4. D.51 units
Show answer
Correct answer: C. 35 units

Of every hundred units of insolation arriving at the top of the atmosphere, about thirty-five are turned back before they can heat the ground, twenty-seven from the tops of clouds, two from snow and ice covered surfaces and the remainder scattered by the atmosphere; this reflected share is the albedo…

Q3566.General ScienceEasy

The centripetal acceleration of a body moving in a circle of radius r with uniform speed v is directed:

  1. A.Along the tangent, in the direction of motion
  2. B.Towards the centre of the circle
  3. C.Away from the centre of the circle
  4. D.Vertically downward
Show answer
Correct answer: B. Towards the centre of the circle

In uniform circular motion the magnitude of the velocity does not change, so the acceleration can have no component along the direction of motion; the whole of it is perpendicular to the velocity and points to the centre, which is why it is called centripetal, meaning centre seeking, and its…

Q3567.General ScienceMedium

A cyclist leans inward while taking a turn because:

  1. A.It reduces the weight of the cycle
  2. B.The reaction of the ground then has a horizontal component towards the centre of the turn
  3. C.It increases the rolling friction of the tyres
  4. D.It makes the centrifugal force disappear
Show answer
Correct answer: B. The reaction of the ground then has a horizontal component towards the centre of the turn

To move along a curve a body needs a force directed towards the centre of that curve.

Q3568.General ScienceEasy

Ball bearings are used in machines mainly because they:

  1. A.Convert rolling friction into sliding friction
  2. B.Convert sliding friction into rolling friction
  3. C.Remove friction altogether
  4. D.Increase the normal reaction on the shaft
Show answer
Correct answer: B. Convert sliding friction into rolling friction

A shaft turning directly inside a sleeve slides against it, and sliding friction is large; placing hard steel balls between the shaft and its housing makes the surfaces roll over one another instead, and rolling friction is a small fraction of sliding friction, so less energy is wasted and the…

Q3569.General ScienceHard

On a frictionless banked road, the angle of banking for a curve of radius r and a speed v is given by the tangent of the angle equal to:

  1. A.v squared divided by r g
  2. B.r g divided by v squared
  3. C.v divided by r g
  4. D.v squared multiplied by r g
Show answer
Correct answer: A. v squared divided by r g

On a banked road the normal reaction is tilted, its vertical component balances the weight and its horizontal component supplies the centripetal force; dividing one equation by the other leaves the tangent of the banking angle equal to the square of the speed divided by the radius multiplied by the…

Q3571.General ScienceAsked in: Delhi · 7 Sept 2021, Shift 3Medium

A car travels in a circular motion. Which of the following statements is true?

  1. A.Distance travelled by the car will always be less than displacement of the car.
  2. B.Distance travelled by the car will always be more than displacement of the car.
  3. C.Distance travelled by the car will always be equal to displacement of the car.
  4. D.Distance travelled by the car will be zero when displacement is zero.
Show answer
Correct answer: B. Distance travelled by the car will always be more than displacement of the car.

Distance is the length of the actual path and displacement is the straight line from the start to the finish, so on a curved path the two can never be equal: the arc of a circle is always longer than the chord joining its ends.

Q3574.General ScienceEasy

For the same pair of surfaces, which of the following types of friction is the smallest?

  1. A.Static friction
  2. B.Limiting friction
  3. C.Sliding friction
  4. D.Rolling friction
Show answer
Correct answer: D. Rolling friction

When a body rolls, the surfaces in contact change continuously and the irregularities have no time to interlock deeply, so rolling friction is very much smaller than sliding friction; this single fact is the reason the wheel was invented and the reason a ball bearing is fitted wherever a shaft…

Q3575.General ScienceMedium

Which of the following statements about the coefficient of friction is correct?

  1. A.It is measured in newton
  2. B.It has no unit and no dimensions
  3. C.It is measured in newton per square metre
  4. D.It is measured in joule
Show answer
Correct answer: B. It has no unit and no dimensions

The coefficient of friction is the ratio of the limiting or kinetic frictional force to the normal reaction, and since both are forces the ratio is a pure number; the same reasoning applies to other ratios such as the refractive index and relative density.
