A body executes simple harmonic motion. The potential energy (P.E), the kinetic energy (K.E) and energy (T.E) are measured as a function of displacement `x`. Which of the following statements is true?

Options

A. `PE` is maximum when `x= 0`
B. `KE` is maximum when `x= 0`
C. `TE` is zero when `x= 0`
D. `KE` is maximum when `x` is maximum

Answer

B

Explanation

in `S.H.M` at mean position i.e. at `x= 0` kinetic energy will be maximum and `pE` will be minimum Total energy is always constant
