Railway GK Questions 2026

Static GK in railway exams starts with one shared block: Class 10 science. Every RRB exam on GK24 tests it. Group D has 25 questions on Physics, Chemistry and Life Sciences of 10th CBSE level. JE has 30 in CBT-1 and another 15 on Physics and Chemistry in CBT-2. ALP tests General Science in CBT-1 and Basic Science and Engineering in CBT-2, and NTPC lists general science up to 10th inside General Awareness. Beyond science, the lists differ. NTPC names history and the freedom struggle, geography, polity, the economy, art and culture, environment, computers, abbreviations, transport systems in India, world organisations and government bodies. JE names geography, history and culture, polity, the economy and environmental issues, and adds computers and pollution control in CBT-2. This page holds GK24's topic-wise GK notes for railway exams in English and Hindi: General Science, History, Geography, Polity, Economy, Art and Culture, Environment, Computers and static GK, including Indian Railways. Each note is short facts and tables that can be revised in one sitting. Begin with the science notes, since they serve every railway exam, then add the static topics your exam lists, and test each note with its quiz.

Q3509.General ScienceAsked in: UPSC Civil Services · CSE Prelims 2021, GS Paper IEasy

Which one of the following is a reason why astronomical distances are measured in light-years?

  1. A.Distances among stellar bodies do not change.
  2. B.Gravity of stellar bodies does not change.
  3. C.Light always travels in straight line.
  4. D.Speed of light is always same.
Show answer
Correct answer: D. Speed of light is always same.

. A light-year works as a unit of distance only because light in a vacuum always travels at the same speed, so the distance it covers in a year is fixed.

Q3510.Indian EconomyAsked in: UPSC Civil Services · CSE Prelims 2016, GS Paper IEasy

Pradhan Mantri MUDRA Yojana is aimed at

  1. A.bringing the small entrepreneurs into formal financial system
  2. B.providing loans to poor farmers for cultivating particular crops

Q3511.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IMedium

Which of the following statements regarding Carnot engine is/are correct?

1. It is an irreversible engine operating between two temperatures T1 (source) and T2 (sink).

2. Its efficiency is given by η = 1 − T2/T1, where T1 is the temperature of source and T2 is the temperature of sink.

Select the answer using the code given below.

  1. A.1 only
  2. B.2 only
  3. C.Both 1 and 2
  4. D.Neither 1 nor 2
Show answer
Correct answer: B. 2 only

A Carnot engine is an ideal reversible engine, not an irreversible one, and its efficiency is 1 − T2/T1 with temperatures in kelvin.

Q3513.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IMedium

Which one among the following statements is correct?

  1. A.The total mechanical energy of a system is conserved if the forces, doing work on it, are conservative.
  2. B.The total mechanical energy of a system is conserved if the forces, doing work on it, are non-conservative.
  3. C.The total mechanical energy of a system remains constant.
  4. D.Every force encountered in mechanics does have an associated well-defined potential energy.
Show answer
Correct answer: A. The total mechanical energy of a system is conserved if the forces, doing work on it, are conservative.

When only conservative forces do work on a system, the sum of its kinetic and potential energy stays the same; this is the principle of conservation of mechanical energy.

Q3514.GeographyAsked in: UPSC CAPF · CAPF 2025, Paper IEasy

The seasonal variations in the amount of solar energy that any place on the Earth receives are influenced by

  1. A.the speed of rotation of the Earth
  2. B.pollution
  3. C.cloudiness
  4. D.the inclination of the Earth about its axis
Show answer
Correct answer: D. the inclination of the Earth about its axis

Because the axis is tilted and keeps pointing the same way as the Earth goes round the Sun, each place gets more sunlight in one half of the year and less in the other.

Q3515.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IMedium

For a particle in uniform circular motion (radius R and angular velocity ω), the magnitude and direction of acceleration, respectively are

  1. A.ωR, along the radius outward
  2. B.ωR, towards the centre of the circle
  3. C.ω²R, towards the centre of the circle
  4. D.ω²R, along the linear velocity
Show answer
Correct answer: C. ω²R, towards the centre of the circle

In uniform circular motion the speed stays the same but the direction keeps turning, and that change needs an acceleration pointing to the centre.

Q3516.Computer AwarenessAsked in: UPSC CAPF · CAPF 2025, Paper IEasy

1 gigabyte in binary system is equivalent to

  1. A.1000 kilobytes
  2. B.1024 megabytes
  3. C.1200 megabytes
  4. D.10000 kilobytes
Show answer
Correct answer: B. 1024 megabytes

In the binary system every step up the ladder of memory units is a factor of 2 raised to 10, that is 1024, so one gigabyte holds 1024 megabytes.

Q3517.General ScienceAsked in: UPSC CAPF · CAPF 2026, Paper IEasy

A uniform current-carrying narrow solenoid produces

  1. A.uniform magnetic field inside the solenoid
  2. B.uniform magnetic field outside the solenoid
  3. C.magnetic field with straight field lines in all the regions
  4. D.magnetic field with oscillating nature
Show answer
Correct answer: A. uniform magnetic field inside the solenoid

Inside a long, narrow solenoid the field lines run straight and parallel and are evenly spaced, which is the picture of a uniform field.
