Statement I: Moment of inertia of circular ring about a given axis is more than moment of inertia of the circular disc of same mass and same size, about the same axis.
Statement II: The circular ring is hollow, so its moment of inertia is more than circular disc which is solid.
In the light of the above statements, choose the most appropriate answer from the options given below.
Text Solution
Verified by ExpertsD
Both Statement I and Statment II are correct.
In the case of circular ring, the mass is concentrated on the rim, at maximum distance from the axis, therefore moment of inertia increases, as compared to that in circular disc.
