A circular disc is rotating about its own axis
at the rate of 200 revolutions per minute. Two
particles P,Q of disc are at distances 5cm,
10cm from axis of rotation. The ratio of
angular velocities of P and Q is
1) 1:2 2) 1:1 3 :1 4) 4:1
A stationary wheel starts rotating about its
0.​

Answer 1

Answer:

Angular frequency = f = 200rpm

Angular speed = ω = 2πf = 400π rad/min

During circular motion particles of the system revolves with angular velocity , but they have different tangential velocity

angular velocity of P = angular velocity of Q

ω of P/ω of Q = (400πrad/min)/(400πrad/min) = 1:1
