Question

Assuming that the potential energy of spring is zero when it is stretched by x 0 , then its potential energy when it is compressed by x 0 2 is, 3 8 k x 0 2, - 3 4 k x 0 2, - 3 8 k x 0 2, 1 8 k x 0 2

MARKS App · Accepted Answer

Change in potential energy is independent of frame of reference. ∴ U 2 - U 1 = 1 2 k x 0 2 2 - 1 2 k x 0 2 = - 3 8 k x 0 2
