Physics - Rotation Question with Solution | TestHub

A ceiling fan rotates about its own axis with some angular velocity. When the fan is switched off, the angular velocity becomes${\left(\frac{1}{4}\right)}^{th}$of the original in time$t$and$n$revolutions are made in that time. The number of revolution made by the fan during the time interval between switch off and rest are (Angular retardation is uniform)
