A circular turn table has a block of ice placed at its centre. The system rotates with an angular speed ω\omega 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
View answer and explanation
Correct option: D
Decreases to a value less than ω\omega
Option D (Decreases to a value less than ω\omega) is correct because the moment of inertia increases as the ice melts and spreads out, conserving angular momentum.
