A tiny dipole of dipole moment p is placed at a distance r from an infinetely long wire with its p normal to the wire. If the linear charge density of the wire is h, the electrostatic force of attraction acting on the dipole is equal to

if dipole length is 2a, dipole moment is p, relative permitivity ε & force is f than

f=hlp/4πε(r2+a2)3/2
