4 2 A long horizontal wire AB which is free to move in a vertical plane and carries a steady current of 20A is in equilibrium at a height of 0 01m over another parallel long wire CD which is fixed in a horizontal plane and carries a steady current of 30A as shown in figure 4 248 Show that when AB is slightly depressed it executes simple harmonic motion Find the period of oscillations i 20A B
