Question

A body moving in simple harmonic motion has minimum acceleration when it has

maximum potential energy.

maximum displacement.

minimum kinetic energy.

maximum velocity.

minimum velocity.

Answer 1

Correct option is D. Maximum velocity.

Reason: body moving in SHM will have minimum acceleration at the point after which it's velocity starts decreasing (maximum velocity), if acceleration continues to increase, than body will never move in SHM. So minimum acceleration will be when it has maximum velocity.

All the rest of the options are same point in SHM, as PE is maximum at maximum displacement and there velocity is minimum, and kinetic energy is also minimum.
