A long straight conductor AB, carrying a current of 25 A is fixed horizontally. Another long conductor XY is kept parallel to AB at a distance of 4mm, in air. Conductor XY is free to move and carries current 1. Then the magnitude and direction of current I forwhich the magnetic repulsion just balances the weight of conductor XY is (Mass per unit length for conductor XY is `5 xx 10^(-2) Kg//m)`.
