A ball with charge 50 e is placed at the centre of a hollow spherical shell which has a net charge of - 50 e . What is the charge on the shells outer surface?

Question

A ball with charge 50 e is placed at the centre of a hollow spherical shell which has a net charge of - 50 e . What is the charge on the shells outer surface? (A) -50e (B) Zero (C) -100e (D) +100e

The net charge on the outer surface is -(50 e-50 e)=100 e

Q. A ball with charge $50 e$ is placed at the centre of a hollow spherical shell which has a net charge of $- 50 e$ . What is the charge on the shells outer surface?

-50e

Zero

-100e

+100e

The net charge on the outer surface is $- (50 e - 50 e) = 100 e$

Q. A ball with charge 50e is placed at the centre of a hollow spherical shell which has a net charge of −50e . What is the charge on the shells outer surface?
