The vector sum of two forces is perpendicular to their vector difference. In this case, the two forces:
1. Are equal
2. Have the same magnitude
3. Are not equal in magnitude
4. Cannot be predicted
If the angle between the vector is \(\theta\), the value of the product is equal to:
1. zero
2. BA2\(\sin\theta \cos \theta\)
3. BA2\(\cos\theta\)
4. BA2\(\sin\theta\)
The vectors are such that: .
The angle between the two vectors is:
1. \(90^\circ\)
2. \(60^\circ\)
3. \(75^\circ\)
4. \(45^\circ\)
\(\overrightarrow{A}\) 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. | \(90^{\circ}\) |
