A circular table rotates about a vertical axis with a constant angular speed \( \omega \). A circular pan rests on the turn table (with the centre coinciding with centre of table) and rotates with the table. The bottom of the pan is covered with a uniform small thick layer of ice placed at centre of pan. The ice starts melting. The angular speed of the turn table
(a) remains the same
(b) decreases
(c) increases
(d) may increase or decrease depending on the thickness of ice layer
