STANDARD Physics Moment of Inertia MCQ Question
Type: MCQ-conceptual-Medium
Which of the following has the highest moment of inertia when each of them has the same mass and the same radius?
A
A ring about any of its diameter.
B
A disc about any of its diameter.
C
A hollow sphere about any of its diameter.
D
A solid sphere about any of its diameter.
Correct Answer
Option C
Detailed Explanation
The moment of inertia of a hollow sphere about any of its diameter is larger than that of a ring, disc, or solid sphere with the same mass and radius. This is because the mass distribution is farther from the axis of rotation.
