In a simple harmonic oscillator, at the mean position                                              [AIEEE 2002]

A)  kinetic energy is minimum, potential energy is maximum

B)  both kinetic and potential energies are maximum

C)  kinetic energy is maximum, potential energy is minimum

D)  both kinetic and potential energies are minimum 

Correct Answer: C

Solution :

[c] Kinetic energy of a particle of mass m in SHM at any point  and potential energy  where, a is amplitude of particle and  is the distance from mean position.

So, at mean position,

(maximum)

and                                (minimum)
