A) \[60{}^\circ \]
B) \[90{}^\circ \]
C) \[0{}^\circ \]
D) \[45{}^\circ \]
E) \[30{}^\circ \]
Correct Answer: D
Solution :
\[|\overrightarrow{A}\times \overrightarrow{B}|=|\overrightarrow{A}.\overrightarrow{B}|\] \[\Rightarrow \] \[AB\sin \theta \hat{n}=AB\cos \theta \hat{n}\] \[\Rightarrow \] \[\tan \theta =1\] \[\Rightarrow \] \[\theta =45{}^\circ \]You need to login to perform this action.
