Gauss' Law for Electricity

In point form, the first of Maxwell’s equations, called Gauss’ law (electric), is a similar expression for the electric field  , but its divergence is not zero,             ----------------------- [4284] where,            ρ -- Charge            ε0 -- Permittivity of of vacuum, 8.854 × 10−12 farad/m
