Question

A hollow metal sphere of radius 5 cm is charged such that the potential at its surface is 10 V. The potential at a distance of 2 cm from the centre of the sphere is:

• A. zero
• B. 10 V
• C. 4 V
• D. (10)/(3) V

Hint:

Electric field inside a conductor is zero, but potential is constant.

Answer 1

The Correct Option is B

Step 1: Property of conducting sphere. Inside a conductor, electric potential remains constant.
Step 2: Applying the concept. Potential at every interior point equals surface potential.
