A current carrying circular loop of wire is placed in a magnetic field \(B\), which makes an angle \(\theta\) with the normal to the loop. The radius of the loop is \(r\), and the loop carries a current \(i\). The magnetic interaction energy of the current carrying loop is \(E_B\) and the torque on the loop has the magnitude \(\tau_B\).
Which of the following, is independent of \(\theta?\)
1. \(E_B\cdot\tau_B\)
2. \(\frac{E_B}{\tau_B}\)
3. \(E_B^2+\tau_B^2\)
4. \(E_B^2-\tau_B^2\)

Given below are two statements:
| Assertion (A): | Gauss's law for magnetism states that the net magnetic flux through any closed surface is zero. |
| Reason (R): | The magnetic monopoles do not exist. North and South poles occur in pairs, allowing vanishing net magnetic flux through the surface. |
| 1. | (A) is true but (R) is false. |
| 2. | (A) is false but (R) is true. |
| 3. | Both (A) and (R) are true and (R) is the correct explanation of (A). |
| 4. | Both (A) and (R) are true but (R) is not the correct explanation of (A). |
