Dancing Loop

A uniform circular loop (string) of radius $R_{0} = 5\text{ cm}$ and negligible thickness is rotating clockwise with a tangential speed $v_{0}=10\text{ cms}^{-1}$ . Find the speed of waves travelling on this loop in $\text{cms}^{-1}$ .

Details and Assumptions:

• Assume a gravity free space/surrounding.

• Consider the mass per unit length of the string as $0.25\text{ gcm}^{-1}$ .
