Some types of molecules that do not possess an intrinsic electric dipole moment

Question

Some types of molecules that do not possess an intrinsic electric dipole moment can be given one by an external electric field in a process called charge separation, or polarization. In this process their internal charge distribution becomes distorted by the field, with the result that the region of a molecule on the side in the direction of the field gains a positive net charge, while the region on the other side gains a negative net charge. Both charges have equal magnitudes and the electric neutrality of the molecule as a whole is maintained. The electric field is said to induce an electric dipole moment in such a molecule. When the field is canceled, the molecule reverts to its unpolarized state and loses its electric dipole moment.

Let us model the electric behavior of such a molecule by a pair of

Explanation / Answer

SINCE THE MOLECULE IS KEPT IN A ELECTRIC FEILD SO

force due to elec. field=force due to spring

i.e qE = kX

so q=1.6 x 10^-19

E=6.41
