Question

When a metallic spherical shell of radius 20 cm is charged, the potential on its surface is found to be 5 V. The potential at a point 10 cm from the centre of the spherical shell is:

• A. 10 V
• B. 2.5 V
• C. 1.25 V
• D. 5 V

Hint:

Inside a conducting shell, electric field is zero and potential is constant everywhere.
