If there is only one type of charge in the universe, thenvec( E)rightarrow Electric field , vec(ds)rightarrow Area vector

Answer»

`ointvecE.vec(DS)ne0` on any surface
`ointvecE.vec(ds)` could not be defined
`ointvecE.vec(ds)=oo` if CHARGE is INSIDE
`ointvecE.vec(ds)=0` if charge is outside, = `(q)/(in_(0))` if charge is inside

Solution :`vecE.vec(ds)ne0` any surface
If charge is outside the surface, incoming flux = OUTGOING flux. Net flux through surface = 0
If charge is inside, flux only goes one way.
