Question

when electric dipole is placed in uniform external electric field electric dipole experiences – motion but the field is non uniform there is dash motion in addition to dash motion​

Answer 1

If you keep a dipole in a uniform electric field then it will experience rotational motion but will not experience any translatory motion however when you keep it in a non uniform electric field it will experience both rotational as well as translational motion because the net force acting on a dipole will be non zero ...
