Question

A simple pendulum of period T on the earth is brought to the moon.if the ratio of the acceleration due to gravities of the earth and the moon is 6 the period of oscillation of the pendulum on the moon is

Answer 1

The period of simple pendulum

T=2π√(l/g)

So

T_E=2π√(l/g_E )

T_M=2π√(l/g_M )

T_M/T_E =√(g_E/g_M )=√6=2.4

T_M=2.4T_E
