Two solid discs of radii `r` and `2r` roll from the top of an inclined plane without slipping. Then

A metal disc of radius R and mass M freely rolls down from the top of an inclined plane of height h without slipping. The speed of its centre of mass on reaching the bottom of the inclined plane is

Three bodies, a ring, a solid disc and a solid sphere roll down the same inclined plane without slipping. The radii of the bodies are identical and they start from rest. If V_(S), V_(R) and V_(D) are the speeds of the sphere, ring and disc, respectively when they reach the bottom, then the correct option is

A solid cylinder of mass M and radius R rolls down an inclined plane without slipping. THE speed of its centre of mass when it reaches the bottom is

A solid sphere, solid cylinder and a disc are allowed to roll down from the top of an incline plane from the same height. Then

A ring ( R ), a disc ( D ), a solid sphere ( S ) and a hollow sphere with thin walls ( H ), all having the same mass but different radii, start together from rest at the top of inclined plane and roll down without slipping. Then

A ring ( R ), a disc ( D ), a solid sphere ( S ) and a hollow sphere with thin walls ( H ), all having the same mass but different radii, start together from rest at the top of inclined plane and roll down without slipping. Then
