it states that in a given volume V surrounded by conductors or for that matter infinity if the charge density [tex]\rho[/tex] and the charge on each conductor is fixed then the electric field is uniquely determined in that volume V(adsbygoogle = window.adsbygoogle || []).push({});

Can someone use this find the field in certain situations.

For Example consider this classical situation where in an uncharged conductor has a cavity of arbitrary shape inside it which has a point charge q inside it .The question is to find the net fieldoutsideit .

Ofcourse the answer is shielding by the metallic sphere ?

Can someone prove this using the uniqueness theorem .I have a proof in mind but i am unsure of it?
