Question

A solid copper sphere has a charge of $0.4C$ placed on it.The charge distribution for the sphere is?

• A. The charge is equally distributed throughout the entire sphere
• B. The charge is concentrated inside the sphere with some charge on the outside
• C. The charge is equally distributed on the outside surface of the sphere
• D. The charge is equally distributed throughout the inside of the sphere only
• E. The charge is concentrated in the center of the sphere

Answer 1

The correct option is C The charge is equally distributed on the outside surface of the sphere

We know that charge on a conductor equally distributes on its outer surface, infact charges go to their final possible position of rest due to electrostatic force of repulsion and that is surface of conductor (metal), therefore a charge of $0.4C$ will equally distributes on the outside surface of the sphere.
