A hollow conducting sphere is placed in an electric field produced by a point charge placed at P as shown in figure. Let V A , V B , and V C be the potentials at points A , B and C on the sphere respectively.

- As a property of conductor, In static situation, potential at all the points of the conductor is same i.e. whole conductor is equipotential.
- Since the sphere is a conductor, and all three points A, B and C lie on the its surface, which is equipotential.
- Therefore,

V_{A} = V_{B} = V_{C}

Q. A hollow conducting sphere is placed in an electric field produced by a point charge placed at $P$ as shown in figure. Let $V_{A}, V_{B}$ , and $V_{C}$ be the potentials at points $A, B$ and $C$ on the sphere respectively. Then :.

$V_{C} > V_{B}$

$V_{A} > V_{B}$

$V_{B} > V_{C}$

$V_{A} = V_{B} = V_{C}$
