A long straight conductor PQ, carrying a current of 60 A, is fixed horizontally. Another long conductor XY is kept parallel to PQ at a distance of 4 mm, in air. Conductor XY is free to move and carries a current I. Calculate the magnitude and direction of current I for which the magnetic repulsion just balances the weight of conductor XY. (Mass per unit lengths for conductor XY is 10-2 kg/m).
