30 Two concentric circular loops one of radius R and the other of radius 2R lie in the xy plane with the origin as their common center as shown in the figure The smaller loop carries current I in the anti clockwise direction and the larger loop carries current 1 in the clockwise direction with 12 21 B x y denotes the magnetic field at a point x y in the xy plane Which of the following statement s is are correct y R 12 12 2R B x y is perpendicular to the xy plane at any point in the plane 2 B x y depends on x and y only through the radial distance r x y 3 B x y is non zero at all points for r R
