Question

Which of the following statements is/are true? (A) A clock when taken on a mountain can be made to give correct time if we change the length of pendulum suitably (B) An increase in value of g makes a clock go slow (C) If the length of a pendulum is increased, the clock becomes fast (D) A clock when taken to a deep mine or carried to the top of a mountain becomes slow

Above or below the earth's surface, value of acceleration due to gravity decreases, so time period (T=2 π √(l/g)) increases ie, clock will become slow.

An increase in value of g makes a clock go slow

If the length of a pendulum is increased, the clock becomes fast

A clock when taken to a deep mine or carried to the top of a mountain becomes slow

Above or below the earth's surface, value of acceleration due to gravity decreases, so time period $(T = 2 π \frac{l}{g})$ increases ie, clock will become slow.
