Problem 3. ZA P a) Find the potential of a thin disk of radius R cov- ered with a surface charge density o at a point P = (0, 0, z) on its axis of symmetry as shown. b) Then expand the result to leading order in the two limits R » z and z » R and in- terpret/identify the potentials in both of these cases.
