Coulomb Law From Gauss Law derivation

Gauss’s law for electrostatics is used for determination of electric fields in some problems in which the objects possess spherical symmetry, cylindrical symmetry,planar symmetry or combination of these. Let us discuss the applications of gauss law of electrostatics:

1. Electric Field Due To A Point Charge Or Coulomb’s Law From Gauss Law:-

To derive Coulomb’s Law from gauss law or to find the intensity of electric field due to a point charge +q at any point in space using Gauss’s law ,draw a Gaussian sphere of radius r at the centre of which charge +q is located (Try to make the figure yourself).
