Angular Velocity

A circular di...

Question

A circular disc is rotating about its own axis at the rate of $200$ revolutions per minute. Two articles $P . Q$ of disc are at distances $5 c m, 10 c m$ from axis of rotation, The ratio of angular velocities of $P$ and $Q$ is:

Solution

as P and Q are on the disc therefore the angular velocity of each and every particle on disc will be same therefore ratio of angular velocities is 1:1
