Question

A hollow metal sphere of radius R is uniformly charged. The electric field due to the sphere at a distance r from the centre 

(1) Increases as r increases for r < R and for r > R 

(2) Zero as r increases for r < R, decreases as r increases for r > R 

(3) Zero as r increases for r < R, increases as r increases for r > R 

(4) Decreases as r increases for r < R and for r > R

Answer 1

The correct option is (2) Zero as r increases for r < R, decreases as r increases for r > R.

Explanation:

Charge Q will be distributed over the surface of hollow metal sphere.
