A uniform ball of radius r is placed on the top of a sphere of radius R = 10 r. It is given a slight push due to which it starts rolling down the sphere without slipping. The spin angular velocity of the ball when it breaks off from the sphere is omega=sqrt((p)/(q)((g)/(r))) , where g is the acceleration due to gravity and p and q are the smallest integers. What is the value of p+q ?
