A) the angular velocity of the system decreases
B) the angular velocity of the system increases
C) the angular velocity of the system remains unchanged
D) the moment of inertia of the system decreases
Correct Answer: A
Solution :
The water obtained after melting of ice, will move away from the axis of rotation (due to centrifugal force), so the moment of inertia (J) of the system increases. As, there is no external torque on the system, so,\[I\omega =cons\tan t\] Here,\[I\]increases, so\[\omega \](angular velocity) will decrease.You need to login to perform this action.
