A long straight conductor AB carries a current of 50 A  and is fixed horizontally. Conductor CD lies parallel to AB at a distance of 5 cm in air. If CD carries a current I, calculate its magnitude of which it balances the weight of the conductor CD (Considering mass per unit length for conductor CD is 10-2 kg/m)
