Railway GK Questions 2026

This is the feature that sets the platform apart from a conventional news agency, because a small newspaper can run a national or international story under its own masthead without attributing it to the broadcaster.

Free access has been stretched in steps rather than granted once and for all, which is exactly what makes this a favourite question.

PBSHABD is its free news feed, and the very name carries the parent body in it, since it expands to Prasar Bharati - Shared Audio-Visuals for Broadcast and Dissemination.

The support is deliberately paid month by month over the same six months that now make up the minimum placement period, so that the money helps a candidate stay in a new job and a new city rather than arriving as one lump sum.

The Ministry of Rural Development started the scheme on that date to give placement-linked skill training to youth of 15 to 35 years from poor rural households, and the scheme is marking its twelfth anniversary this year.

Under the earlier design of the scheme a placement counted only when the trained candidate held continuous employment for at least three months, so option A states the old rule and not the present one.

A lactometer floats in milk and shows its relative density. Pure milk is denser than water, so adding water lowers the density and the instrument sinks deeper, which reveals the adulteration.

The horsepower is an older practical unit of power that survives in the rating of engines, pumps and motors, and it equals about 746 watts.

The mole is the chemist's counting unit: one mole of any substance contains the Avogadro number of particles, about six followed by twenty-three zeros, whether those particles are atoms, molecules or ions.

A barometer measures the pressure of the atmosphere, traditionally by balancing it against a column of mercury. It is also used for forecasting weather, because a sudden drop in pressure signals an approaching storm, and for finding altitude, since pressure falls as one rises.

Work is force multiplied by displacement. Force has the dimensions M L T⁻², and multiplying it by a length adds one more power of L, which gives M L² T⁻².

Pressure is force divided by area, so its unit is one newton per square metre, which is given the name pascal after Blaise Pascal.

A light year is the distance that light, moving at about three lakh kilometres per second, covers in one year, which works out to roughly 9.46 trillion kilometres.

The candela takes its name from the candle, which was once used as a rough standard of light, and it is one of the seven base units of the SI system.

The newton is a derived unit: it is built from the kilogram, the metre and the second, since force equals mass times acceleration, and it can be written as one kilogram metre per second squared.

The SI system, adopted in 1960 by the General Conference on Weights and Measures, rests on seven base units: the metre, the kilogram, the second, the ampere, the kelvin, the mole and the candela.

One newton is the force that gives a mass of one kilogram an acceleration of one metre per second squared, which follows directly from the equation force equals mass times acceleration.

The Harappan script uses about four hundred picture-like signs, and it was written in the boustrophedon style, that is from right to left in the first line and then from left to right in the next, turning like an ox ploughing a field.

Dholavira stands on Khadir island in the Rann of Kutch. Unlike the usual two-part Harappan town, it is divided into three: a citadel, a middle town and a lower town, all enclosed by stone walls.

The seal shows a figure seated in a yogic posture with horns on its head and animals around it, usually described as an elephant, a tiger, a rhinoceros and a buffalo, with deer below the seat.
