A ring of mass M and radius R is rotating with angular speed ω about a fixed vertical axis is passing through its center O with tow points masses each of mass

at rest at O.These masses can moves radially outwards along two massless rods fixed on the rings as shown in figure.At some instant the angular speed of the system is

ω and one of the masses is at distance of

R from O.At this instant the distance of the other mass from O is .
