Question

A heavy metal sphere is suspended from a spring. When pulled down a little and released, it oscillates up and down with a frequency f. If it is taken to the moon (where the acceleration due to gravity is one-sixth that on earth) the frequency of vertical oscillation will

Solution

Correct option is

Remain unchanged

Since the frequency of the vertical oscillations is independent of the acceleration due to gravity.
