2. The following figure shows a cross-section through a cylindrical conducting shell with radius R. The shell is infinite in extent along the z-axis perpendicular to the page and is divided into four quadrants that are insulated from one other another. Suppose that the quadrant that spans the angle ó = -T/4 to o = T/4 is held at a constant potential Vo, while the other quadrants are held at V =0. Find: (a) The potential inside the shell (b) The charge density induced on the inner surface of the shell.
