MCQ
The angular momentum of a system of particles is not conserved when:
- ANet external force acts on the system.
- BNet external torque acts on the system.
- CNet external impulse acts on the system.
- DNone of the above.
✓
Answer
- Net external torque acts on the system.
Explanation:
As $\omega=\frac{2\pi}{\text{T}}$ and time period T for both the particles is same, therefore, their angular velocity must be the same.
