A ring disc and solid sphere are having same speed of COM at the bottom of incline as shown in the figure. If surface of incline is sufficiently rough. The ratio of height attend by ring, disc and sphere is

Mention the position of centre of mass of ring. Disc and spheres.

If a ring, a disc, a solid sphere and a cyclinder of same radius roll down an inclined plane, the first one to reach the bottom will be:

If a ring, a disc, a solid sphere and a cyclinder of same radius roll down an inclined plane, the first one to reach the bottom will be:

A solid sphere, disc and hollow sphere are placed at the top of an inclined plane. Surface is sufficiently rough to provide pure rolling. All the objects are released from a state of rest

A nollow sphere and a solid sphere having same mass and same radii are rolled down a rough incline plane.

A ring, a solid cylinder and a solid sphere, all having same mass and radius, are placed at the top of an incline and released. The friction coefficents between the objects and the incline are same and not sufficient to allow pure rolling. ( a ) Which body will reach the bottom first? ( b ) Which body will have the minimum kinetic energy at the bottom?
