A conducting sphere of radius R is placed in a uniform electric field E0 directed along the +z axis. The electric potential for outside points is given by Vout = -E0(1 - (R/r)3)r cosθ, where r is the distance from the center and θ is the polar angle. The charge density on the surface of the sphere is:
