A) L is \[\bot \] to \[\pi \]
B) L lies in \[\pi \]
C) L is paralel to \[\pi \]
D) None of these
Correct Answer: B
Solution :
[b] Since \[3(1)+2(-2)+(-1)(-1)=3-4+1=0\] \[\therefore \] Given line is \[\bot \] to the normal to the plane i.e., given line is parallel to the given plane. Also \[(1,-1,3)\] lies on the plane \[x-2y-z=0\]if \[1-2(-1)-3=0\] i.e. \[1+2-3=0\] Which is true \[\therefore \] L lies in plane\[\pi \].You need to login to perform this action.
