A) \[\vec{E}\] must be the electric field due to the enclosed charge
B) If net charge inside the Gaussian surface \[=0,\] then \[\vec{E}\] must be zero everywhere over the Gaussian surface.
C) If the only charge inside the Gaussian surface is an electric dipole, then the integral is zero.
D) E is parallel to \[\overrightarrow{dA}\] everywhere over the Gaussian surface.
Correct Answer: C
Solution :
\[\phi =\frac{{{Q}_{net}}}{{{\varepsilon }_{0}}}\] For dipole \[{{Q}_{net}}=0\Rightarrow \phi =0\]
