Physics Question on Oscillations

The potential energy of a weightless spring compressed by a distance a is proportional to

A

aa

B

a2{{a}^{2}}

C

a−2{{a}^{-2}}

D

a0{{a}^{0}}

Answer

a2{{a}^{2}}

Explanation

Solution

The potential energy of a weightless spring compressed by a distance aa is given by U=12mω2a2U=\frac{1}{2} m \omega^{2} a^{2} or U∝a2U \propto a^{2}
