Practice question

Given: A uniform disk of mass 3 kg and radius 0.6 m rotates about its nter. What is its moment of inertia? Formula: For a uniform disk: I = 1/2 M R². Substitution & Calculation: M = 3 kg, R = 0.6 m . I = 1/2 × 3 × (0.6)² = 1.5 × 0.36 = 0.54 kg m² . Final Result: The computed value matches expected outcome and confirms correct choice as per latest NCERT 2026-27.
