## Gauss’s Law-

Before you go through this article, make sure that you have gone through the previous article on Gauss’s Law.

We have learnt-

• Gauss’s Law helps to find the total electric flux through any closed surface.
• It states that the total electric flux through any closed surface is 1/εo times the net charge enclosed within it.

In this article, we will discuss the proof of Gauss’s law.

## Gauss’s Law Proof-

Consider an isolated point charge +Q placed at a point O. We draw a spherical Gaussian surface of radius R with O as the center and calculate the electric flux from it.

The electric field intensity due to charge +Q at every point on the Gaussian surface is given by-

The electric flux over the entire closed Gaussian surface is given by-

This proves Gauss’s law in electrostatics.
