Charge is distributed with uniform surface charge density sigma on a circular disc with radius a. the disc lies in the xy plane with center at the origin. find the electric field at a point (o, o, z) on the z-axis. explicitly calculate the limiting forms of the solution at very small (z < < a) and at very large (z > > a) z compared to a.
