Question

A hollow metal sphere of radius $5cm$ is charged so that the potential on its surface is $10V$. The potential at the center of the sphere is

• A. 0 $V$
• B. 10 $V$
• C. Infinity
• D. same as at point 25 $cm$ away from the surface

Answer 1

The correct option is B 10 $V$

Potential inside the hollow sphere is always same as there on the surface.
