Charged disk; was electrostatig

[Ludwik Kowalski <KowalskiL@MAIL.MONTCLAIR.EDU>]

As I explained a minute ago, it is better to avoid a cyliner
because it has sharp edges. To be realistic you must
assume they are not "infinitely sharp" and intruduce
the radius of curvature at some level. I suggested that
we do this at the level of the thickness. The surface
of the disk becomes smooth.
