A) (-3, 2)
B) (2, -3)
C) (-2, 3)
D) (3, -2)
Correct Answer: A
Solution :
\[\overrightarrow{a}\bot \overrightarrow{b}\therefore \overrightarrow{a}.\overrightarrow{b}=0\] \[\overrightarrow{b}\bot \overrightarrow{c}\therefore \overrightarrow{b}.\overrightarrow{c}=0\] \[2\lambda +4+\mu =0\] ?.(1) \[\overrightarrow{a}\bot \overrightarrow{c}\therefore \overrightarrow{a}.\overrightarrow{c}=0\] \[\lambda -1+2\mu =0\] ...(2) solving (1) and (2), we get \[\lambda =3\] \[\mu =2\]You need to login to perform this action.
