# Electric Field Inside Conductor: Charge Density on Conductor

APPHEM-MR\$YKE

A hollow conducting sphere has a net charge of +Q. A smaller point charge, +q, is located a distance r from the left side of the hollow sphere.

Point P is located on the right side of the sphere; and point T is located somewhere on the inside of the sphere, not necessarily in the center.

What happens to the charge density on the hollow sphere at point P and to the electric field at point T as the point charge, +q, is brought closer to the hollow sphere?

A

The charge density at P decreases. The electric field at T remains zero.

B

The charge density at P remains zero. The electric field at T remains zero.

C

The charge density at P increases. The electric field at T increases in magnitude and always points to the right.

D

The charge density at P increases. The electric field at T remains zero.

E

The charge density at P remains constant but nonzero. The electric field at T remains constant and points to the left.
