I'm about to start my first time teaching the unit on Electricity, for the
Ontario grade 12A Physics course, which opens with electrostatics.
If a charged object is spherical, the charge is uniformly distributed over
the surface, the reason for this distribution is quite clear. What isn't
immediately apparent, this Biochemist is, why charge becomes concentrated
around sharp pointed areas on a conductor's surface.
Explanation please.

I thank whoever it was on this Listserv, or a chemistry Listserv I
subscribe to, that made the graphic I have only slightly altered. It has
inspired both positive comments, and variations.
