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