What is an equipotential in an electric/gravitational field?
Equipotentials are lines of constant potential. In radial fields they join points of equal potential and are perpendicular to the field lines.
They are concentric spherical surfaces about the centre of the body and get further apart because the field gets weaker - you move a greater distance before you get the same ΔV.
