At a point on the axis of an electric dipole

A point charge placed at any point on the axis of an electric dipole at some large distance experiences a force F. What will be the force acting on the point charge when its distance from the dipole is doubled.

If a point charge placed at any point on the axis of an electric dipole at some large distance experiences a force F, then what force will act on the point charge when its distance from the dipole is doubled ?
