Question

A hollow metallic sphere of radius $10 c m$ is given a charge of $3.2 \times 10^{- 9} C$ . The electric intensity at a point $4 c m$ from the centre is

Open in App

Solution

The electric field intensity at $4 c m$ from the centre is 0.
As all the charge reside at the surface of the sphere and have electric field at any point inside the sphere to zero which results in net field on the charge due to sphere .
