Which of the following statements is correct:

Options

A. In simple harmonic motion, additional potential energy of the once in one time period
B. In simple harmonic motion, constant force have no effect on time period.
C. A block can't perfome SHM, if frictionless force acts on it.
D. Average acceleration in one time period of a SHM is non zero.

Answer

B

Explanation

Time period of a particle performing SHM is independent of applied force if force is constant. Net displacement in one time period of SHM is constant hence average velocity and and average acceleration in one time period of SHM is zero.
