Q. The figure shows a system consisting of (i) a ring of outer radius 3R rolling clockwise without slipping on a horizontal surface with angular speed

ω

and (ii) an inner disc of radius 2R rotating anticlockwise with angular speed

\frac{ω}{2} .

The ring and the disc are separated by frictionless ball bearings. The system is in the xz-plane. The point P on the inner disc is at a distance R from the origin, where OP makes an angle of

30^{\circ}

with this horizontal, where O is the centre of the disc. Then with respect to this horizontal surface

The figure shows a system consisting of (i) a ring of outer radius 3R rolling clockwise without slipping on a horizontal surface with angular speed $ω$ and (ii) an inner disc of radius 2R rotating anti-clockwise with angular speed $\frac{ω}{2}$ . The ring and disc are separated by frictionless ball bearings. The system is in the x - z place. The point P on the inner disc is at distance R from the origin O, where OP makes an angled of 30 $^{\circ}$ with the horizontal. Then with respect to the horizontal surface,
