A) \[-\frac{13}{4}\]
B) \[-\frac{17}{4}\]
C) \[4\]
D) None of these
Correct Answer: A
Solution :
[a] Since line is parallel to the plane vector \[2\vec{i}+3\vec{j}+\lambda \vec{k}\] is perpendicular to the normal to the plane \[2\vec{i}+3\vec{j}+4\vec{k}\] \[\Rightarrow 2\times 2+3\times 3+4\lambda =0\] or \[\lambda =-\frac{13}{4}\]You need to login to perform this action.
