Question 212 of 280
A mass hangs on a massless rod of length which rotates at a constant angular frequency. The mass moves with steady speed in a circular path of constant radius. Assume that the system is in steady circular motion with constant angular velocity The angular momentum of about point is which lies in the positive direction and the angular momentum of about is The correct statement for this system is:
Show answer and solution
Answer: (D) is constant, both in magnitude and direction
We know,
Now with respect to we always get direction
of along -axis and also constant magnitude as mvr. But with respect to we get constant magnitude but continuously changing direction.
