[Phys-l] Disc polarizability



In Strong's text Hull claims the polarizability of a metal disc is (2/3) the permitivity (space) times its diameter cubed. Finding this for a sphere and even an infinite cylinder is trivial (once one has seen it done). But a disc, no. Anyone know how it's done (not numerically)? I've looked in many texts *, googled and not found it.


* not the best, unfortunately,

bc, wonders, will JD come to his rescue?
