Consider a spherical gaussian surface of radius r centered at the origin. a 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 x = r/2, y = 0, z = 0.
(b) at the origin.
(c) at x = 0, y = 0, z = r/2.
(d) at x = 0, y = r/2, 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.
