Text Solution
Verified by ExpertsThe correct answer is:
A
Initial angular momentum of ring 
If four object each of mass m , and kept gently to the opposite ends of two perpendicular diameters of the ring then final angular momentum = 
By the conservation of angular momentum
Initial angular momentum = Final angular momentum
⇒ ⇒
