Two circular coils, each having 1000 turns and radius R =0.25 ~m , are placed co-axially. Each coil is separated by a distance 1.0 m from the point P as shown in the figure. The coils carry equal currents 2.0 A in the same direction. An identical configuration of coils is placed perpendicular to the previous arrangement as shown in the figure. The magnitude of magnetic field at point P is closest to
