want a brief on gauss's law ,proof and application

The total of the electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity.




Gauss' law is a powerful tool for the calculation of electric fields when they originate from charge distributions of sufficient symmetry to apply it.

Gauss' LawGaussian surfaces

If the charge distribution lacks sufficient symmetry for the application of Gauss' law, then the field must be found by summing the point charge fields of individual charge elements. Examples are:

Finite line chargeCharged ringCharged disc
