The potential energy of a particle executing `SHM` change from maximum to minimum in `5 s`. Then the time period of `SHM` is:

Options

A. `5s`
B. `10s`
C. `15s`
D. `20s`

Answer

D

Explanation

`P.E` is maximum at exteement position and minimum at mean position.
Time to go from extreme position to mean position is `,t=(T)/(4),` where `T` is time period of `SHM 5s=(T)/(4)`
`rArr T=20s`.
