A) \[\frac{1}{2}\]
B) \[2\]
C) \[1\]
D) \[\lambda \in R-\{0\}\]
Correct Answer: B
Solution :
[b] \[1=\left| (\vec{b}-\vec{a}).\frac{(\vec{p}\times \vec{q})}{\left| \vec{p}\times \vec{q} \right|} \right|\Rightarrow \left| \vec{a}-\vec{b} \right|\cos 60{}^\circ =1\] \[AB=2\]You need to login to perform this action.
