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