The figure shows two cases A and B where in case A ring of radius R is rotating with angular velocity w about its axis at rest while in case B a ring is doing pure rolling on a horizontal surface with angular velocity w Find the ratio of radius of curvature of point Q as seen from point P on ring at the given moment in case A to the absolute radius of curvature of Q in case B R P A B R
