Question

# A linear simple harmonic oscillation has a total mechanical energy of 300 J. Its potential energy at mean position is 100 J. Find the minimum potential energy.

A
50 J
B
250 J
C
100 J
D
200 J

Solution

## The correct option is C 100 JGiven, Total mechanical energy (E)=300 J Potential energy at mean position (U)=100 J We know, at mean position, potential energy is minimum. Hence, Umin=100 J
