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