  3. Question 3

    Rotational Dynamics. Asked once: 19 May 2026 S2

    106
    A ring of mass MM and radius RR is rotating with angular speed ω\omega about a fixed vertical axis passing through its centre OO with two point masses each of mass M8\dfrac{M}{8} at rest at OO. These masses can move radially outwards along two mass-less rods fixed on the ring as shown in figure. At some instant the angular speed of the system is 8ω9\dfrac{8\omega}{9} and one of the masses is at a distance of 35R\dfrac{3}{5}R from point OO. At this instant, the distance of the other mass from point OO is
