A hollow sphere and a solid sphere having same mass and same radii are rolled down a rough inclined plane.

Four round objects namely a ring, a disc, a hollow sphere and a solid sphere with same radius R and made of same material start to roll down an inclined plane at the same time. The object that will reach the bottom third is

A solid sphere, a hollow sphere and a disc, all having the same mass and radius, are placed at the top of an incline and released. The friction coefficients between the objects and the incline are same and not sufficient to allow pure rolling. The least time will be taken in reaching the bottom by

A solid sphere, a ring and a disc all having same mass and radius are placed at the top of an incline and released. The friction coefficient between the objects and the incline are same but not sufficient to allow pure rolling. Least time will be taken in reaching the bottom by

four round objects namely a ring , a disc ,a hollow sphere and a sphere with same radius R start to roll down an incline at the same time .find out the order of objects reaching the bottom first ?

A solid sphere and a hollow sphere of the same material and of equal radii are heated to the same temperature.

A solid sphere, disc solid cylinder all of the same mass and made of the same material are allowdd to roll down (from rest) on the inclined plane, then:
