A positive test charge is placed at the center of a spherical Gaussian surface.
What happens to the net flux through the Gaussian surface for each of the following
cases?
(a) The surface is replaced by a cube of
the same volume whose center is at the same
point.
(b) The sphere is replaced by a cube of one-
third the volume centered at the same point.
