Is executing simple harmonic motion with frequency n the frequency of its potential energy?

A body is executing simple harmonic motion with frequency ‘n’, the frequency of its potential energy is

(1) n (2) 2n (3) 3n (4) 4n

Solution: Answer (2)

Displacement equation of SHM of frequency ‘n’ is:

x = Asin(ωt) = Asin(2πnt) 

So the frequency of potential energy = 2n
