Question

What is gausss law

Answer 1

In electrodynamics, Gauss's law, also known as Gauss's flux theorem, In its integral form, it states that the flux of the electric field out of an arbitrary closed surface is proportional to the electric charge enclosed by the surface, irrespective of how that charge is distributed.

$\oint \vec Ed\vec A=\frac{1}{\epsilon_0}\sum q_i$ or $\oint \vec Dd\vec A=\sum q_i \ \ (\vec D=\epsilon_0\vec E)$
