(B) The work done $W$ by a conservative force $\vec{F}$ is related to the change in potential energy $V$ by the relation: $W = -\Delta V$. Given that the work done is positive $(W > 0)$,we have $-\Delta V > 0$,which implies $\Delta V Since $\Delta V = V_{final} - V_{initial} Therefore,the potential energy of the body decreases when a conservative force does positive work on it.
