question_answer

A particle is executing simple harmonic motion with angular frequency\[\omega \]then angular frequency of its kinetic energy will be:

A)  \[\omega \]                      

B)         \[\omega /2\]   

C)  \[2\omega \]                                   

D)         \[4\omega \]

Correct Answer: D

Solution :

In one oscillation of particle kinetic energy changes four times. So, the frequency of kinetic energy \[=4\omega \]
