A hollow metal sphere of radius is charged such that the potential on its surface is The potential at the centre of the sphere is
Step 1. Given data
Potential on the surface
Radius of the sphere
Step 2. Formula used
Where is the charge and is the permeability and is the radius
Step 3. Find the potential at the center of the sphere
Hence, the potential at the center of the sphere is
Let re the radius of the sphere the electric field and the potential, is the charge
if the electric field will be zero for the metallic charged sphere.
if the potential will be constant throughout the metallic charged sphere.
