Lecture 7 : GAUSS'S LAW
  GAUSS'S LAW - Integral form
The flux calculation done in Example 4 above is a general result for flux out of any closed surface, known as Gauss's law.
  Total outward electric flux $\phi$through a closed surface $S$is equal to $1/\epsilon_0$times the charge enclosed by the volume defined by the surface $S$

  Mathematicaly, the surface integral of the electric field over any closed surface is equal to the net charge enclosed divided by $\epsilon_0$
