Marks: +1, -0

A hollow cylinder of radius 4R is rotating about fixed horizontal axis passing through point ' O ' with angular velocity ω0. A solid cylinder of radius 'R' is rolling without slipping with respect to inner surface of hollow cylinder. At the given instant, the line OC has angular velocity of 2ω0. Point A and B are topmost and bottom most point of solid cylinder respectively and C is its centre. Then, at the given instant

Angular velocity of solid cylinder about its own axis is 10ω0 (
Magnitude of acceleration of point A of solid cylinder is 88ω02R (
Magnitude of acceleration of point B of solid cylinder with respect to contact surface of hollow cylinder is 112ω02R (
Radius of curvature of point A is ‌
