If there were only one type of charge in the universe, then
Options:
(a) `oint_0^1 vec E cdot vec (ds)≠0` on any surface.
(b) `oint_0^1 vec E cdot vec (ds)=0` if the charge is outside the surface.
(c) `oint_0^1 vec E cdot vec (ds)` could not be defined.
(d) `oint_0^1 vec E cdot vec (ds)=q/epsilon_0` if charges of magnitude q were inside the sur
