Answer 1

A man standing on a rotating table is holding two masses at arm's length without moving his arms, he drops to masses then his angular speed will increase.

● In the above mentioned case the external force applied is zero. So the moment of inertia decreases as he drops the the masses.

● this leads to the increase in the angular velocity or speed of the person.

constantτ external =0 ⟹L=Iw=constant.

Answer 2

His angular speed will increase.

Explanation:

Angular momentum :

Angular momentum is equal to the product of moment of inertia and angular velocity.

In mathematically,

$L=I\omega$

Torque :

Torque is equal to the product of force and distance.

In mathematically,

$\tau=F\times r$

We need to calculate the angular speed

When a man drops two masses without moving his arm then the torque is

$\tau =o$

$L = I\omega = constant$

The moment of inertia decreases and angular speed will increase.

Hence, His angular speed will increase.
