The time rate of change of angular momentum of a particle equals the:
ATraction on it
BTremor in it
CTorque on it
DTension in it
Answer & Solution
Correct answer: C. Torque on it
1. This is the rotational counterpart of force equalling rate of change of momentum.
2. The rotational counterpart of force has its own name.
3. The time rate of change of the angular momentum of a particle is equal to the torque acting on it.
4. So the answer is the torque on it.
