Q. No.Vectors \(\vec {\mathrm{A}}, \vec{\mathrm{B}} \) and \(\vec{\mathrm{C}}\) are such that \(\vec{\mathrm{A}} \cdot \vec{\mathrm{B}}=0 \text { and } \vec{\mathrm{A}} \cdot \vec{\mathrm{C}}=0\). Then the vector parallel to \(\vec A\) is:
| 1. | \(\vec{A} \times \vec{B} \) | 2. | \(\vec{B}+\vec{C} \) |
| 3. | \(\vec{B} \times \vec{C} \) | 4. | \(\vec{B}~\text{and} ~\vec{C}\) |

\(\overrightarrow{A}\) and \(\overrightarrow B\) are two vectors and \(\theta\) is the angle between them. If \(\left|\overrightarrow A\times \overrightarrow B\right|= \sqrt{3}\left(\overrightarrow A\cdot \overrightarrow B\right),\) then the value of \(\theta\) will be:
| 1. | \(60^{\circ}\) | 2. | \(45^{\circ}\) |
| 3. | \(30^{\circ}\) | 4. | \(90^{\circ}\) |
