00:00Question says if a body covers 3 revolutions in 6 seconds then its angular velocity in

00:15SI units will be a 2 pi radian per second b 4 pi radian per second c 6 pi radian per

00:25second d pi radian per second is angular velocity omega is calculated by using formula delta

00:38theta upon delta t. So angular displacement for one complete cycle is given as 2 pi radian

00:54so for 3 revolutions it will be 3 into 2 pi radian. So angular velocity will be obtained

01:08as by placing the value of angular displacement 3 into 2 pi radian divided by time which is

01:20obtained as 6 seconds the table of 3 on 3 is 1 times and on 6 is 2 times and 2 will

01:28be get cancelled with 2. So angular velocity for 3 revolutions in 6 seconds will be obtained

01:36as pi radian per second so the correct option will be d pi radian per second.
