Question
Why does a larger moment of inertia result in smaller angular acceleration for a given torque?
Explanation
From τ = Iα, angular acceleration α is inversely proportional to moment of inertia I. A larger I means more resistance to rotation, reducing α for the same torque. As per NCERT, applying relevant law/formula with correct units and sign convention leads to Because it resists angular acceleration more. This satisfies dimensional consistency and physical conditions given, so option B is scientifically correct.
