Right Answer is: A
SOLUTION
- When a conductor is at equilibrium, the electric field inside it is always zero.
- Since the electric field is equal to the rate of change of potential, the voltage (potential) inside a conductor at equilibrium is constant at the value it reaches the surface of the conductor.
- We take a charged conducting sphere as shown to understand this:
