A) \[\frac{q}{{{\varepsilon }_{0}}}\]
B) \[\frac{2q}{{{\varepsilon }_{0}}}\]
C) \[\frac{q}{2{{\varepsilon }_{0}}}\]
D) zero
Correct Answer: D
Solution :
(d) zero As net charge on a dipole is \[\left( -q+q \right)=0\] Thus, when a Gaussian surface encloses a dipole, as per Gauss's theorem, electric flux through the surface, \[\oint{\overrightarrow{E}\,.}\,d\,\overrightarrow{S}=\frac{q}{{{\varepsilon }_{0}}}=0\]
