1.	A spherical ball of mas m is kept at the highest point in the space between two fixed, concentric spheres A and B as shown in figure. The sphere A has radius R and sphere B has radius R+d. All surfaces are smooth. The diameter of ball slightly less than d. The ball is given a gentle push so thatangle made by radius vector of the ball with vertical is theta. N_(A) and N_(B) are the magnitudes of normal reaction forces on the ball exerted by spheres A and B respectively. The match the following
