    A Gaussian sphere encloses an electric dipole within it. The total flux across the sphere is

    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 \[\text{o }\!\!|\!\!\text{ =}\frac{q}{{{\varepsilon }_{0}}}+\left( \frac{-q}{{{\varepsilon }_{0}}} \right)=0\] Note: As Gaussian surface is not a enclosed surface, hence the question should have been an enclosed surface and not a Gaussian surface.
