Question

Draw an equipotential surface due to an electric dipole.

Answer 1

Equipotential surfaces (or lines in 2-D) are the regions where the potential due to charges remains constant. They are always formed perpendicular to the given point

Answer 2

equipotential surface is the region in space where every point on it is at same electrical potential.

we have to show equipotential surface due to an electric dipole. electric dipole is the system of two same magnitude but opposite nature charges which are seperated very small distance from each other.

so, an electric dipole have two opposite nature charge. straight line passing through centre of electric dipole will be equipotential surface as shown in figure. hence, graph of equipotential surface due to dipole will be a straight line.
