Consider a spherical Gaussian surface of radius R centered at the origin: charge Q is placed inside the sphere. To maximize the magnitude of the flux of the electric field through the Gaussian surface, the charge should be located:
A) at the origin
B) at x=0, y=0, z=R/2
C) at x=0, y=R/2, z=0
D) at x=R/2, y=0, z=0
E) The charge can be located anywhere, since flux does not depend on the position of the charge as long as it is inside the sphere.
