Question

2. A long hollow tube has a cross section which is the pie shaped wedge formed from the x-z plane, the y-z plane, and the curved surfacex y R2. The two flat surfaces are held at zero potential, and the curved surface has a potential V(r,φ)-V, sinp cosp. Find the potential inside the wedge. Extra credit include a 3D graph of the potential.
