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.
