The point charge is located in the center of a spherical Gaussian surface (the surface penetrated by the desired flow of the electrostatic field strength vector E). Will this flow change if a) the surface is replaced by a cube of the same volume as the sphere; b) displace the charge from the center of the sphere, leaving it inside the sphere; c) move the charge outside the sphere; d) leave the removed charge near the original sphere, and place a second charge outside it; e) place the second charge inside the same Gaussian surface.
