Lying in the plane x + y + z = 6isa line L passing through (1,2, 3) and perpendicular to the line of intersection of planes x + y + z = 6 and2x - y + z = 4, then the equation of L is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
C
Required line lies in the plane x + y + z = 6 so it is perpendicular to 
and it is also perpendicular to line of intersection of the two given planes.
Let, 
& 
be a vector along the required line
So, 
Hence, equation of the line is
