If there were only one type of charge of...

If there were only one type of charge of the universe then

A

`oint_(s)vecE.dvecsne0` on any surface

B

`oint_(s)vecE.dvecs=0` if the charge is outside the surface

C

`oint_(s)vecE.dvecs=q/(epsilon_(0))` if charges of magnitude q were inside the surface

D

both (b) and ( c) are correct

Text Solution

Verified by Experts

The correct Answer is:
D
According to Gauss's theorem in electrostatics
`oint vecE*vec(ds)=q/epsilon_(0)`
Here q is charge enclosed by the surface.
If the charge is outside the surface, therefore `q_("inside")=0`
Also, `ointvecE*dvecs=0`.
So both (b) and ( c) are correct.
