A current-carrying loop is placed in magnetic field as shown in figure. What is the time period of small oscillation about an axis passing through diameter of the coil?
(Mass of coil is \(m\), radius is \(R\))
(Mass of coil is \(m\), radius is \(R\))
| 1. | \(2 \pi \sqrt{\dfrac{m}{I B}} \) | 2. | \( \sqrt{\dfrac{2 \pi m}{I B}} \) |
| 3. | \( 2 \pi \sqrt{\dfrac{I}{m B}}\) | 4. | \(2 \pi \sqrt{\dfrac{m}{2 / B}}\) |

Select the correct option based on the statements:
| Statement I: | The magnetic field of a circular loop at very far away point on the axial line varies with distance as like that of a magnetic dipole. |
| Statement II: | The magnetic field due to magnetic dipole varies inversely with the square of the distance from the centre on the axial line. |
| 1. | Statement I is correct and Statement II is incorrect. |
| 2. | Statement I is incorrect and Statement II is correct. |
| 3. | Both Statement I and Statement II are correct. |
| 4. | Both Statement I and Statement II are incorrect. |
