Two very thin concentric rings lies in the xy-plane with their centers at the origin. The outer ring has a current of 1.5 A in the +uφ direction and has a radius of 50 cms. The inner ring has a radius of 30 cms. The magnetic field at the point (0, 0, 1 m) is zero. Find the current in the inner ring.
