A fan is making 600 revolutions per minute. If after some time it makes 1200 revolutions per minute, then increase in its angular velocity is

View answer and explanation

Correct option: B

20\;\pi \;rad/sec

Option B (

20\;\pi \;rad/sec

) is correct because it is the difference between the final and initial angular velocities after converting revolutions per minute to radians per second.
