Inside the sphere there is no electric field.‭ ‬Where the outside electric field meets the surface of the sphere,‭ ‬the electric field must be normal to the surface of the sphere.‭ ‬Otherwise,‭ ‬the electric field at the surface would have a vector component parallel to the surface which would cause charge to move along the surface,‭ ‬again in violation of our static conditions stipulations.‭ ‬Now,‭ ‬electric fieldha lines tt are perpendicular to the surface of a sphere lie on lines that pass through the center of the sphere.‭ ‬Hence,‭ ‬outside the sphere,‭ ‬the electric field lines form the same pattern as the pattern that would be formed by a point charge at the location of the center of the sphere‭
