4. The potential at the surface of a sphere (radius R) is given by V₀=k cos3θ where k is a constant. Find the potential inside and outside the sphere, as well as the surface charge density σ(θ) on the sphere. (Assume there's no charge inside or outside the sphere.) (A)cosθ[140cos²θ - 93] (B)cosθ[140cos²θ] (C)cosθ[140cosθ - 93] (D)cosθ[140cos²θ - 93]
