MHT CET Physics question
A ceiling fan rotates about its own axis with some angular velocity. When the fan is switched off, the angular velocity becomes of the original in time 't' and n revolutions are made in that time. The number of revolutions made by the fan during the time interval between switch off and rest are (Angular retardation is uniform) [MHT-CET 2023, MHT-CET 2023]
Answer: (C)
Solution
the angle turned in time t is (n revolutions) and the total angle to rest is
