Whitney Says That Gauss's Law Can Be Used to Find

Multiple Choice

Whitney says that Gauss's Law can be used to find the electric field of a sufficiently symmetrical distribution of charge as long as
Over the whole Gaussian surface.Algie says that the electric field must be a constant vector over the entire Gaussian surface.Which one,if either,is correct?

A) Whitney,because that means no charge is enclosed within the Gaussian surface.
B) Algie,because a constant electric field means that .
C) Both,because the conditions in (a) and (b) are equivalent.
D) Neither,because the electric field can be found from Gauss's law only if holds only over a portion of the Gaussian surface.
E) Neither,because the charge distribution must be symmetric if anywhere on the surface.
