Consider three bodies : a ring, a disc and a sphere. All the bodies have same mass and radius. All rotate about their axis through their respective centre of mass and perpendicular to the plane. What is the ratio of moment of inertia ?

the body which is having greater moment of inertia will have more angular acceleration

the body which is having greater moment of inertia will have lower angular acceleration

both will accelerate with same magnitude

None of these

Consider four bodies-a ring, a cube, a disc and a sphere. All the bodies have the same diameter, equal to the length of the cube on ech edge.All rotate about their axes through their respective centres of mass. Which one has the largest moment of inertia?

Ring

Cube

Disc

Sphere

`(I)/(2)`

`(I)/(sqrt2)`

`I + MR^(2)`

`1//2MR^(2)`

`MR^(2)`

`1//4MR^(2)`

`3//4 MR^(2)`
