A) zero
B) half that due to a single charge
C) double that due to a single charge
D) dependent on the position of the dipole
Correct Answer: A
Solution :
Total electric flux through enclosed surface \[\text{o }\!\!|\!\!\text{ }\,\text{=}\frac{q}{{{\varepsilon }_{0}}}+\left( \frac{-q}{{{\varepsilon }_{0}}} \right)=0\] Note: As Gaussian surface is not a enclosed surface, hence the question should have been 'an enclosed surface' and not a Gaussian surface.
