Question : 11

Total: 54

Two identical ring I and | of equal mass ' m ' and radius ‌∘R′ are moving in opposite direction with linear speed ωR and 2ωR respectively. Rings are rotating with equal angular speed in opposite direction. The line joining the centres make an angle of 30∘ with the velocity. Then, at the given instant (AB=6R)

The angular momentum of ring 1 about point P is 2mR2ω
The angular momentum of ring I about point Q is 7mR2ω
The angular momentum of ring II about point Q is 2mR2ω
The angular momentum of ring II abput point P is 15mR2ω
