FrozenT [24]

Answer:

Explanation:CE

Let after the fall of weight from hands , the moment of inertia reduces from 2I to I. Since no external torque is acting on the system , angular momentum will be conserved.

I₁ ω₁ = I₂ ω₂

2I ω₁ = I ω₂

2ω₁ = ω₂

So , angular velocity will be doubled.

Option A is correct.
