Two uniform circular discs having the same mass and the same thickness but different radii are made from different materials. The disc with the smaller rotational inertia is

Two discs of same thickness but of different radii are made of two different materials such that their masses are same. The densities of the materials are in the ratio of 1 : 3. The moments of inertia of these discs about the respective axes passing through their centres and perpendicular to their planes will be in the ratio of

Two discs A and B have same mass and same thickness but A is made of aluminium and B is made of lead. Which has larger moment of inertia about the central axis?

Two discs A and B have same mass and same thickness but A is made of aluminium and B is made of lead. Which has larger moment of inertia about the central axis?

Assertion (A) Two circular discs of equal mass and thickness made of different materials, will have same moment of inertia about their central axes of rotation. Reason (R) Moment of inertia depends upon the distribution of mass in the body.

(A) : Two circular discs of equal masses and thickness made of different material, will have same moment of inertia about their central axes of rotation. (R ) : Moment of inertia depends upon the distribution of mass in the body.
