15 When there is a net static charge present on an isolated perfect conductor
(A)the charge will be uniformly distributed over the surface of the conductor.
(B)the surface charge density will be greatest where the conductor is flat and smallest where there are sharp points.
(C)the electric field inside the conductor needs not be zero if the conductor is hollow.
(D)every point throughout the entire conductor will be at zero potential.

(E)every point throughout the entire conductor will be at a constant potential, but not necessarily at zero potential.
