A fly wheel rotates about a fixed axis and slows down from 300 rpm to 100 rpm in 2 min. Then its angular retardation in rad /

{\min ^2}

⁡is

View answer and explanation

Correct option: D

200

\pi

Option D (200 π) is correct because angular retardation is the change in angular velocity divided by the time interval.
