Question

The electric field inside a charged hollow sphere is 

A) 1 

B) 0

C) Infinite 

D) Negative

Answer 1

The correct option is (B) 0

To find field inside the hollow sphere we can take Gaussian surfaces with radii ranging from R=0 to R=r. 

Any of these surfaces the charge enclosed is zero and hence field at all the points on these surfaces is zero. Thus, electric field inside a hollow sphere of conductor is zero.
