Question

Normal 0 false false false EN-US X-NONE X-NONE 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 · Accepted 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.
