A) \[\frac{\pi }{4}\]
B) \[\frac{\pi }{2}\]
C) \[\pi \]
D) zero
Correct Answer: B
Solution :
\[(\overrightarrow{A}+\overrightarrow{B})\]is in the plane of A and B, but\[\overrightarrow{A}\times \overrightarrow{B}\]is always perpendicular to the plane of\[\overrightarrow{A}\]and\[\overrightarrow{B}\]both, so angle between\[(\overrightarrow{A}+\overrightarrow{B})\]and \[(\overrightarrow{A}\times \overrightarrow{B})\]is\[\frac{\pi }{2}.\]You need to login to perform this action.
