1.	A pendulum clock gives correct time at the equator. Will it gain or lose time if it is taken to the poles ? Why?
Answer» Solution :When a pendulum clock showing CORRECT TIME at equator is taken to poles then it will gain time. Acceleration due to gravity at poles is high. Time period of pendulum `T = 2PI sqrt(l/g)` When g INCREASES T decerases. So DECREASES . So number of oscillations made in the given time increases hence clock gains time.
