What is the ratio of magnitudes of their angular velocities, ω1/ω2? express your answer in terms of the variables r1 and r2?

We are using the formula: v = rω Please consider that they have the same tangential velocity at their edges. Therefore we can equate: r1 ω1 = r2 ω2 And re-arrange: ω1 / ω2 = r2 / r1
