Select the correct statement. In a conservative force field

Moderate

A

if the potential energy of a body is zero, net force acting on the body must be zero
B

if potential energy of the body is minimum, net force acting on the body may not be zero.
C

if potential energy of a body is zero, net force acting on the body may not be zero
D

none of the above statements is correct

Solution

Conservative force acting on a body is given by $F = - \frac{d U}{d r}$ . So if U is zero, rate of change of potential energy with displacement may not be zero. Also when U = 0, rate of change of potential energy with displacement may not be zero.
