Hello Friends,
in my textbook it is written that in electrostatics,electric field(E) due to a conductor at an external point very near to it is given by σ/ε.where 'σ' is the local surface charge density and 'ε' is epsilon.they have derived it by using a symmetrical conductor which have symmetrical charge density.my doubt is that whether this formula is valid for unsymmetrical conductors also or not?if yes,then can anyone explain me why is it so?if possible,then please give me a mathematical derivation.
Thanks
Arvind
