Hard· Dipole in a Non Uniform External Field (Force and Torque on a Finite Dipole)· +4 / −1
A dipole is placed in an electric field as shown. In which direction will it move ?
Figure: the electric field lines diverge from a point on the left and spread out towards the right, so the field is stronger on the left and weaker on the right. The field points to the right along the central line. A dipole lies along the central line with the charge on the left and the charge on its right.
