In a simple harmonic oscillator, at the mean position

A

(a) kinetic energy is minimum, potential energy is maximum.

B

(b) both kinetic and potential energies are maximum.

C

(c ) kinetic energy is maximum, potential energy is minimum.

D

(d) both kinetic and potenteal energies are minimum.

Text Solution

Verified by Experts

The correct Answer is:
C
(c ) `K.E=1/2k(A^(2)-x^(2)), `U=1/2kx^(2)`
At the mean position `x=0`
:. `K.E.=1/2kA^(2)=Maximum and`U=0`.
