Draw an equipotential surface for an electric dipole.

(N/A) An electric dipole consists of two equal and opposite charges,$+q$ and $-q$,separated by a small distance $d$.
An equipotential surface is a surface where the electric potential $V$ is constant at every point.
For an electric dipole,the equipotential surfaces are not spheres.
Near the charges,the surfaces are roughly spherical and centered around each charge.
As we move further away from the dipole,the surfaces become distorted and eventually take the shape of a surface enclosing both charges.
The potential is zero at the perpendicular bisector of the dipole,which forms a plane of zero potential (an equipotential surface with $V = 0$).
In summary,the surfaces are closer together where the electric field is stronger (near the charges) and further apart where the field is weaker.
