A point charge is placed at the center of a spherical Gaussian surface.The electric flux $\phi$ _E is changed if: A)the sphere is replaced by a cube of the same volume B)the sphere is replaced by a cube of one-tenth the volume C)the point charge is moved off center (but still inside the original sphere) D)the point charge is moved to just outside the sphere E)a second point charge is placed just outside the sphere

According to Gauss's law, the electric flux through a closed surface depends only on the charge enclosed within the surface. Moving the charge outside the sphere means it is no longer enclosed, thus changing the flux.
