A) \[\frac{-2}{3}\]
B) \[\frac{-1}{6}\]
C) \[\frac{2}{5}\]
D) \[\frac{1}{3}\]
Correct Answer: C
Solution :
Any point on the line \[B(1-2\lambda ,-1+3\lambda ,5+4\lambda )\] \[\therefore \]Direction ratios AB are \[(-2\lambda ,3\lambda -3,4\lambda +2)\] AB is parallel the normal of the plane \[\frac{-2\lambda }{4}=\frac{3\lambda -3}{9}=\frac{4\lambda +2}{-18}\Rightarrow \lambda =\frac{2}{5}\]Ans.You need to login to perform this action.
