OK I think after all maybe I chose a bad example. The infinite plane of charges creates a divergent integral of the Coulombic potential at x0, I think. And if you take a large sheet of charges, then that integral is probably tending to be constant in x.
Presumably if you have a finite lump of...
Thanks v much for reply.
Hmm no, I don't think I know how to apply Maxwell in that situation. We know Div E = 0 since there is a neighbourhood of x0 with no charge density, and we know -c Curl E = dB/dt, but I don't see where we'd be getting dB/dt to know E that way. Presumably dB/dt should...
Hi. I am trying to understand Maxwell's equations. I am used to Gaussian units. The following sums up what I do not understand. (Or at least one thing I do not understand ... )
Let x0 be a position situated in a vacuum, with no photons in it, next to an infinite pane of glass. Ions arrive at...
