A very small electric dipole with dipole moment p is placed in such in way that it is at a distance r from another point charge +q. The point charge lies on the axis of the dipole . Electric dipole moment is pointing towards the point charge. Determine electric dipole will attract the point charge or repel it ? What will be the magnitude of force between them ?
