Potential Inside a Charged Hollow Metal Sphere – Rankers Physics

Electric Potential: Practice Problem & Solution

A hollow metal sphere of radius 5 cm is charged so that the potential on its surface is 10 V. The potential at the centre of the sphere is :
0 V
10 V
Same as at point 5 cm away from the surface
Same as at point 25 cm away from the surface

Short Solution (Best for NEET):

To solve this problem, we apply the core principles of Electric Potential. Understanding the underlying formula is key to arriving at the correct answer below:

Inside a hollow metal sphere, the electric field is zero. This implies the electric potential is constant throughout the interior and equal to the surface potential of 10 V.
