Here is Your Answer.....!!!!

Actually welcome to the concept of the Electrostatics....

Basically if we look here ...we get to know that ...the dipole is nothing but a thing that has two charges that are of opposite charges but of equal magnitude ...Separated by distance D .....

So actually when a dipole is placed in a electric field ....No force acts .....eventually The torque acts on it .....

The Torque is actually experienced by dipole by the on the position or inclination of the dipole with the effective electric field ....thus there is no force acting on the Dipole ....
