Chapter 22.3, Problem 1FE

Which of the following statements about Gauss’s law is correct? (a) If we know the charge enclosed by a surface, we always know the electric field everywhere at the surface. (b) When finding the electric field with Gauss’s law, we always use a sphere for the gaussian surface. (c) If we know the total flux through a surface, we also know the total charge inside the surface. (d) We can only use Gauss’s law if the electric field is constant in space.
