Question

A hollow insulated conduction sphere is given a positive charge of 10 mC. What will be the electric field at the centre of the sphere if its radius is 2 metres?

(a) Zero

(b) 5 uCm^-2

(c) 20 uCm^-2

(d) 8 uCm^-2

Amit Saxena · Answer

(a)

Charge resides on the outer surface of a conducting hollow sphere of radius R. We consider a spherical surface of radius r < R. By Gauss''s theorem,

i.e., electric field inside a hollow sphere is zero.

Maham Hanif · Answer

Field inside a conducting sphere is zero. Formula of gausses law, Φ=q/∈0 put q=0, final ans will be zero. Hope it helps!
