Question
Find the moment of inertia of a solid sphere 2 m in diameter and of mass 5 kg about an axis passing through the centre.
Correct Answer
Option A is the correct answer.
Detailed Explanation
Radius r = 1 m. For solid sphere, I = (2/5)MR² = (2/5) × 5 × 1² = (2/5) × 5 = 2 kg·m².
Hint
I_solid sphere = (2/5)MR².
