Q. A pendulum clock is placed on the moon, where object weighs only one-sixth as much as on earth, how many seconds the clock tick out in an actual time of 1 minute the clock keeps good time on earth?

A) 12.25
B) 24.5
C) 2.45
D) 0.245
Explanation

(b) $T^{'} = 2\pi\sqrt{l/(g/6)} = \sqrt{6}T$ Hence, the clock will tick in one minute
$= 60/\sqrt{6} = 24.5$ times
