The figure shows mass m moves with velocity u. Find the velocity of ring at that moment. Ring is restricted to move on smooth rod.

Text Solution

Verified by Experts

The correct Answer is:
`V_(R)=(u)/(costheta)," "V_(R)=2u`
Velocity along string remains same .
`V_(R)costheta=u`
`V_(R)=(u)/(costheta)`
`theta=60^(@)`
`V_(R)=2u`
