Rotational MotionHard
Question
A circular turn table has a block of ice placed at its centre. The system rotates with an angular speed w about an axis passing through the centre of the table. If the ice melts on its own without any evaporation, the speed of rotation of the system : -
Options
A.becomes zero
B.remains constant at the same value of ω
C.increases to value greater than ω
D.decreases to a value less than ω
Solution
As ice melts into water, it spreads & moment of inertia increases so angular velocity decreases.
