Fig. shows an electric dipole. A point charge 4 μC is placed on the axial line of dipole at a large distance from the centre of dipole where electric field strength due to dipole is I 00 N/C. The dipole is also present in the electric field of 4 μC charge. Assuming that the charges that make the dipole are fixed relative to each other, but the dipole, as a whole, is free to move :
