Question

what is deduction of gauss law​

Answer 1

Gauss's Law states that the total electric flux out of a closed surface is equal to the charge enclosed divided by the permittivity. The electric flux in an area is defined as the electric field multiplied by the area of the surface projected in a plane and perpendicular to the field. ... ϵ0 = the electric constant.

Answer 2

This is the dedeuction of gauss' law
