A mass M hangs on a massless rod of length l which rotates at a constant angular frequency. The mass M moves with steady speed in a circuilar path of constant radius. Assume that the system is in steady circular motion with constant angular velocity omega . The angular momentum of M about point A is L_(A) , which lies in the positive z direction and the angular momentum of M about point B is L_(B) . The correct statement for this system is :
