The angular momentum of a moving body remains constant if
The angular momentum of a moving body remains constant if
Options
- Anet external force is applied
- Bnet external torque is applied
- Cnet pressure is applied
- Dnet external torque is not applied.
Correct answer
D. net external torque is not applied.
Step-by-step solution
When the net external torque acting on a system is zero, the total angular momentum of the system remains constant. Therefore the angular momentum of a moving body remains constant if net external torque is not applied.
