Two circular rings (of same material) are of same thickness. The diameter of first ring is twice that of second. The moment of inertia of first ring as compared to that of second is

View answer and explanation

Correct option: B

8 times

Option B (8 times) is correct because the moment of inertia is proportional to the mass and the square of the radius, and the mass is proportional to the area.
