Spherical Symmetry

First, a uniform spherical shell, radius r0, of positive charge.
The perfect spherical symmetry means the electric field outside, at a distance r from the center, must point radially outwards. (rotating the sphere doesn’t change anything, but would change a field pointing any other way.)
