Suppose I have a negatively charged plate at -10000v (static) and a neutral plate in front of it; quiet close to it, this charged plate will induce +10000v in the inner surface of this neutral plate right??....or near to that potential difference if the case is not ideal isn’t it??.

And an opposite charge of the same magnitude in the outer surface of this neutral plate….that is -10000v right??

Just confirming….I don’t find things in such details in the net or the books…..I just thought bout……is this true??....this things been a real head ach to me

I doubt if any article has been written on this.
