Type: MCQ-conceptual-Medium
The moment of inertia of two spheres of equal masses about their diameters are equal. If one of them is solid and other is hollow, the ratio of their radii is
A
√3 : √5
B
3 : 5
C
√5 : √3
D
5 : 3
Correct Answer
Option C
Detailed Explanation
For a solid sphere, I = 2/5 MR² and for a hollow sphere, I = 2/3 MR². Equating these and solving for the ratio of radii gives √5 : √3.
