Angular Velocity

Two particles...

Question

Two particles move in concentric circles of radii $r_{1}$ and $r_{2}$ such that they maintain a straight line at the center. Find the ratio of their angular velocities.

Open in App

Solution

Since they maintain a straight line from the centre, their angular velocities are same.
$\Rightarrow ω_{1} = ω_{2}$
It means the ratio of their angular velocities is one.
