Vedclass · Answer

(D) The electric potential $V$ due to a point charge $q$ at a distance $r$ is given by $V = \frac{1}{4\pi\epsilon_0} \frac{q}{r}$.For a constant potential $V$,the distance $r$ must be constant. This defines a sphere centered at the point charge. Therefore,a spherical equipotential surface is possible for a point charge. Thus,the Assertion $(A)$ is false.Inside a spherical capacitor,the electric field is radial,and the equipotential surfaces are spherical shells concentric with the capacitor plates. Therefore,the Reason $(R)$ is true.Since the Assertion is false and the Reason is true,the correct option is $(d)$.

Assertion $(A):$ $A$ spherical equipotential surface is not possible for a point charge.
Reason $(R):$ $A$ spherical equipotential surface is possible inside a spherical capacitor.
