Question

A man standing on a rotating table is holding two masses at arm's length. Without moving his arms, he drops the two masses. His angular speed will

• A. Increase
• B. Decrease
• C. Become zero
• D. Remain constant

Answer 1

The correct option is A Increase

As ${\tau }_{external}=0⟹L=Iw=constant$

Now dropping the masses will decrease Moment of inertia$\left(I\right)$ of the system thus increasing his angular velocity$\left(w\right)$.
