A ring of mass \( M \) and radius \( R \) is rotating with angular speed \( \omega \) about a fixed vertical axis passing through its centre \( \mathrm{O} \) with two point masses each of mass \( \frac{M}{8} \) at rest at \( \mathrm{O} \). These masses can move radially
\( \mathrm{P} \) outwards along two massless rods fixed on the ring as shown in the figure. At some instant the angular speed of the system is \( \frac{8}{9} \omega \) and one of the masses is at a distance of \( \frac{3}{5} \mathrm{R} \) from \( \mathrm{O} \). At this instant the
W distance of the other mass from \( \mathrm{O} \) is
(A) \( \frac{2}{3} R \)
(B) \( \frac{1}{3} \mathrm{R} \)
(C) \( \frac{3}{5} \mathrm{R} \)
(D) \( \frac{4}{5} R \)
