Rotational Motion Question 190
Question: One solid sphere A and another hollow sphere are of same mass and same outer radii. Their moments of inertia about their diameters are respectively and such that Here and represent their densities.
Options:
A)
B)
C)
D)
Show Answer
Answer:
Correct Answer: C
Solution:
[c] In a hollow sphere, the mass is distributed away from the axis of rotation.
So, its moment of inertia is greater than that of a solid sphere.
