A particle is executing simple harmonic motion with a time period T. At time t = 0, it is at its position of equilibrium. The kinetic energy-time graph of the particle will look like

A)

B)

C)

D)

Correct Answer: D

Solution :

[d]: In a simple harmonic motion, velocity of the body is maximum at the equilibrium position. Now, time taken by a particle executing simple harmonic motion to reach extreme position (where velocity of the body is zero) from equilibrium position is 774. Hence, option  is correct.
