Determine the electric field intensity at a point on the axis of an electric dipole. If the dipole is very small, how with the field intensity be modified ?

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 ?

The electric field intensity at a point on the axis of an electric dipole in air is 4 N C^(-1) .Then the electric field intensity at a point on the equatorial line which is at a distance equal to twice the distance on the axial line and if the dipole is in a medium of dielectric constant 4 is
