$\hat k\, + \,\hat j\,$
$\hat i\, + \,\hat j\,$
$3\hat k$
$2\hat i$
If $\overrightarrow A \times \overrightarrow B = \overrightarrow C + \overrightarrow D,$ then select the correct alternative-
The angle between the vectors $\overrightarrow A $ and $\overrightarrow B $ is $\theta .$ The value of the triple product $\overrightarrow A \,.\,(\overrightarrow B \times \overrightarrow A \,)$ is
When $\vec A.\vec B = - |A||B|,$ then
Define the scalar product and obtain the magnitude of a vector from it. Mention the direction of scalar product.
