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 `:`

Text Solution

Verified by Experts

The correct Answer is:
