a long horizontal wire AB, which is free to move in a vertical plane and carries a steady current of 20A, is in equilibrium a a hoeght of 0.01m over another parallel long wire CD which is fixed in ahorizontal plane and carries a current of 30 A. show that when AB is slightly depressed , it executes SHM.
