1.	A man is standing on a rotating table and he drops a heavy mass from his hand outside the table. How will the angular speed of the table change?
Answer» Solution :When the MAN drops the heavy mass from his hand OUTSIDE the table moment of inertia of the system about the axis of rotation decreases. We know that angular momentum = moment of inertia `xx` angular VELOCITY. Since no torque is applied from outside according to the principle of conservation of angular momentum angular velocity of the system will increase dueto DECREASE of its moment of inertia.
