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.

Q15381.General ScienceAsked in: RRB Group D · 13 Sept 2022, Shift 1Medium

Consider the magnitudes and directions of the induced potential difference in the following situations: (a) A magnet moving with a speed of 1 m/s with its north pole towards a stationary coil. (b) The same magnet moving with a speed of 1 m/s with its south pole towards the same stationary coil. The induced potential differences are of ______ magnitude(s) and have ______ sign(s) in the above two cases.

  1. A.the same, the same
  2. B.the same, opposite
  3. C.different, opposite
  4. D.different, the same
Show answer
Correct answer: B. the same, opposite

The same magnet moves at the same speed in both cases, so the rate of change of magnetic flux through the coil is equal and the induced potential difference has the same magnitude.

Q15396.Science & TechnologyMedium

According to the study, how does a black hole jet affect the gas around a galaxy?

  1. A.It cools the gas equally in all directions so that stars form faster
  2. B.It energises the gas only along its own direction and suppresses star formation
  3. C.It pulls the entire gas envelope into the black hole within a few years
  4. D.It has no measurable effect beyond the central region of the galaxy
Show answer
Correct answer: B. It energises the gas only along its own direction and suppresses star formation

When the team averaged their measurements over all directions around the galaxies they picked up no signal, but when they probed along the direction of the jet they found a strong one, which showed that the jet illuminates only the gas in its path.
