The co-ordinates of the foot of perpendicular drawn from point 
to the join of points 
and 
is
A
(5, 7, 1)
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
B
Let D be the foot of perpendicular drawn from 
on the line AB joining (4, 7, 1) and (3, 5, 3).
If D divides AB in ratio 
then 
.....(i)
D.r’s of PD are 
D.r’s of AB are 
; ∴ ∴ 
⇒ ⇒ 
Putting the value of 
in (i), we get the point 
.
