Re: Confused by a derivation.



I have to take a crack at responding.

Carl,
This is a good synopsis of where we stand. Forcing the
superposition of
the fields of the four charge layers to cancel to zero inside both
conductors forces the unique solution.


But Gauss' law, by
its lonesome,
does not require that fields inside conductors be zero,

How do you prove the E field is zero inside an ideal conducting material?

I do it with Gauss' Law (and the electro-static equilibrium assumption).
This tells me that in some fashion Gauss' Law is sufficient for deducing
zero field in the conductor and hence the rest of the arguement.
