Q.
A Gaussian sphere encloses an electric dipole within it. The total flux across the sphere is
AFMCAFMC 2008
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 Gaussian surface.
