Question
By the principle of conservation of angular momentum, when the net external torque acting on a system is zero, the total angular momentum of the system is
Correct Answer
Option D is the correct answer.
Detailed Explanation
The principle of conservation of angular momentum states that if the net external torque on a system is zero, the total angular momentum of the system remains constant (unchanging).
Hint
This is analogous to the conservation of linear momentum when net external force is zero.
