Consider a Gaussian spherical surface covering a dipole of charge \( q \) and \( -q \), then
(1) \( q_{\text {in }}=0 \) (net charge enclosed by the spherical surface)
(2) \( \phi_{\text {net }}=0 \) (net flux coming out the spherical surface)
(3) \( E=0 \) at all points on the spherical surface
(4) \( \oint \vec{E} \cdot d \vec{s}=0 \) (surface integral of over the spherical surface)
