A) \[3x+2y+z+1=0\]
B) \[3x+2y+z=0\]
C) \[2x+3y+\text{ }z=0\]
D) \[x+y+z=0\]
E) none of the above
Correct Answer: B
Solution :
The equation of plane passing through the intersection of given planes is \[(x+2y+3z+4)+\lambda (4x+3y+2z+1)=0\] \[\because \]It passes through the origin, then \[4+\lambda =0\] \[\lambda =-4\] \[\therefore \]Required equation is \[(x+2y+3z+4)-4(4x+3y+2z+1)=0\] \[\Rightarrow \]\[3x+2y+z=0\]You need to login to perform this action.
