Gauss Law: Proofs and Electromagnetism Resources

[Mahmoud Shaban]

about gauss law!

is there any precise proof for gauss law?
why ø=q/ε always regardless how the charge is distributed inside the surface
and if anyone know a good book for electromagnetism please type its name for me..
thank u

Gauss' Law can be derived from Coulomb's Law:

See the Section "Relation to Coulomb's Law" and click on the box for the proof.

Every guassian surface can be described as a point charge. Electric field equals firce field lines per area. So the number of field lines equals e times a.

thank u all
SteamKing, although the proof is complicated for me (advanced calculus for my level) , i`m relieved to know at least that there is a precise proof applicable for all shapes not only spheres! so thank u again

sorry,, i don`t get what you are trying to say..
why would we describe a gaussian surface as apoint charge??
