Let the foot of perpendicular of the point P ( 3, -2, -9) on the plane passing through the points (-1, -2, -3), (9, 3, 4), (9, -2, 1) be Q 
. Then the distance Q from origin is
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
A
Given that three points lie on a plane,
Equation of plane will be,
And the plane passing through, 
Now finding the foot of perpendicular we get,
Distance from origin 
Hence this is the required option.
