Question

A body executes simple harmonic motion. The potential energy (P.E.), the kinetic energy (K.E.) and total energy (T.E.) are measured as a function of time t. Which of the following statements is true. Assume that the particle started at t=0 at its mean position

• A. P.E. is maximum when t = 0
• B. T.E. is zero when t = 0
• C. K.E. is maximum when t = 0
• D. K.E. is minimum when t =T

Answer 1

The correct option is C K.E. is maximum when t = 0

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.
The option (c) is the correct option
