A) \[3x+4y+5z=7\]
B) \[2x+y-2z=0\]
C) \[x+y-z=2\]
D) \[2x+3y+4z=0\]
Correct Answer: B
Solution :
Trick: Since line is parallel to plane if \[al+bm+cn=0\] \[\therefore \] From option , \[3\,(2)+4(1)+5(-2)=0\]. Clearly, \[=\sqrt{400+1600+1600}=60km\] is the required plane.You need to login to perform this action.
