Hi Harshit,

In physics, Gauss law, also known as Gauss flux theorem, is a law relating the distribution of electric charge to the resulting electric field. Gauss law states that:

The electric flux through any closed surface is proportional to the enclosed electric charge.

The law was formulated by Carl Friedrich Gauss in 1835, but was not published until 1867. It is one of the four Maxwells equations which form the basis of classical electrodynamics, the other three being Gauss law for magnetism, Faradays law of induction, and Ampères law with Maxwells correction. Gauss law can be used to derive Coulombs law, and vice versa.
