Answer:Increase
Explanation:
Given
You are holding 2 kg mass in each outstreched hand
If the masses are dropped then Moment of inertia will decease by
Where m=2 kg
r=length of stretched arm
Since angular momentum is conserved therefore decrease in Moment of inertia will result in increase of angular velocity
as I=constant
I=Moment of inertia
=angular velocity
