Question

A particle executes S.H.M. having time period $T$, then the time period with which the potential energy changes is:

• A. $T$
• B. $2T$
• C. $T/2$
• D. $\infty$

Answer 1

The correct option is C $T/2$

The potential energy goes from maximum(at positive end) to Zero(at centre) and again to maximum(at negative end) in one cycle. Hence, its frequency is $2f$ and time period is $T/2$. Option C is correct.
