A ring of mass M and radius R is rotating with angular speed o about a fixed vertical axis passing through its centre O with two point masses each of mass M at rest at O. These masses can move radially outwards along two massless 8 rods fixed on the ring as shown in the figure. At some instant the angular speed 8 of the system is and one of the masses is at a distance of R from O. At 9 5 this instant the distance of the other mass from O is (A) R 2|53|N (C) -R (B) R (D) -R 5
