Electric Dipole in Non-uniform Electric Field…

Electric Dipole in Non-uniform Electric Field – When an electric dipole is placed in a non-uniform electric field, then the two charges of dipole experiences unequal forces. The magnitude of the forces are given in the diagram.
In a non-uniform electric field :
(i) Both force and torque are non-zero.
(ii) Motion of the dipole is translatory and rotatory.
