A ring of radius r is moving without slipping on a circular track of radius R speed of the centre of the ring is `v = omega r`. Ignoring the fact that the ring axis is inclined A. The radial acceleration of centre of the ring is `(omega^(2)r^(2))/(R )`B. The radial acceleration of centre of the ring is `(R-r)^(2)/(R )omega^(2)`C. The angular velocity of centre of the ring about vertical axis passing through the centre of track is `romega//R`.D. The angular velocity of centre of the ring about vertical axis passing through the centre of track is `((R-r))/(R )omega` |
