NEET MCQ Books for XIth & XIIth Physics, Chemistry & BiologyThe one-quarter sector is cut from a uniform circular disc of radius \(R\). This sector has a mass \(M\). It is made to rotate about a line perpendicular to its plane and passing through the centre of the original disc. Its moment of inertia about the axis of rotation will be:
| 1. | \(\frac{1}{2} M R^2 \) | 2. | \(\frac{1}{4} M R^2 \) |
| 3. | \(\frac{1}{8} M R^2 \) | 4. | \(\sqrt{2} M R^2\) |
