Question

Suppose a point charge is located at the center of a spherical surface. The electric field at the surface of the sphere and the total flux through the sphere are determined. Now the radius of the sphere is halved. What happens to the flux through the sphere and the magnitude of the electric field at the surface of the sphere? The flux remains the same, and the field increases. The flux decreases, and the field remains the same. The flux and field both increase. The flux and field both decrease.
