A) \[45{}^\circ \]
B) \[90{}^\circ \]
C) \[180{}^\circ \]
D) \[360{}^\circ \]
Correct Answer: A
Solution :
According to problem, \[|(\overrightarrow{A}.\overrightarrow{B})|=|\overrightarrow{A}\times \overrightarrow{B}|\] or \[AB\text{ }cos\theta =AB\text{ }sin\theta \] or \[tan\text{ }\theta =1\] (as\[AB\ne 0\]) or \[\theta ={{45}^{o}}\]You need to login to perform this action.
