PhysicsEasysingle choice

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 $\frac{x_{0}}{2}$ is

Options:

Answer:

Solution:

Change in potential energy is independent of frame of reference.

$∴ U_{2} - U_{1} = \frac{1}{2} k {(\frac{x_{0}}{2})}^{2} - \frac{1}{2} k x_{0}^{2}$
$= - \frac{3}{8} k x_{0}^{2}$
