Gauss Law: Proofs and Electromagnetism Resources

AI Thread Summary
Gauss's Law can be derived from Coulomb's Law, and it holds true regardless of charge distribution within a surface, with the relationship ø=q/ε being consistent. The discussion highlights a resource, "Introduction to Electrodynamics" by David J. Griffiths, as a recommended book for understanding electromagnetism. Participants express varying levels of comfort with the mathematical proofs, noting that while some find them complex, they appreciate that the law applies to all shapes, not just spheres. The concept of describing a Gaussian surface as a point charge is debated, with some seeking clarification on its relevance. Overall, the conversation emphasizes the foundational nature of Gauss's Law in electromagnetism.

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

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??
 
Thread 'Is there a white hole inside every black hole?'

Thread 'Is there a white hole inside every black hole?'

This is what I am thinking. How much feasible is it? There is a white hole inside every black hole The white hole spits mass/energy out continuously The mass/energy that is spit out of a white hole drops back into it eventually. This is because of extreme space time curvature around the white hole Ironically this extreme space time curvature of the space around a white hole is caused by the huge mass/energy packed in the white hole Because of continuously spitting mass/energy which keeps...

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
