What's a general proof for the log-singularity of electric field near the edge of a uniformly charged surface?

E~-log(r) where r is the distance from the edge –  richard Feb 19 '13 at 19:53
That's for sure explained in Jackson's book. –  A friendly helper Feb 19 '13 at 19:58
I cannot find it there! –  richard Feb 19 '13 at 20:09
Perhaps I'm just a bit confused, but isn't the electric field near an infinite, uniformly charge sheet a constant and equal in magnitude to $\sigma/2\epsilon_0$? Where is this log divergence you speak of? –  joshphysics Feb 19 '13 at 22:49
I second joshphysics' confusion. Do you refer to the edge of a finite charged plane perhaps? –  Michael Brown Feb 20 '13 at 0:51
