In short,
using Coulomb’s law and the superposition principle, electric field can
be determined for any charge distribution, discrete or continuous or part
discrete and part continuous 1 13  GAUSS’S LAW
As a simple application of the notion of electric flux, let us consider the
total flux through a sphere of radius r, which encloses a point charge q
at its centre Divide the sphere into small area elements, as shown in
