Question

The coordinates of the foot of the perpendicular drawn from a point (3, 4, 5) on the xy-plane are
(a) (3, 0, 0)
(b) (0, 4, 5)
(c) (3, 0, 5)
(d) none of these

Answer 1

The co-ordinate of the foot of perpendicular from a point (3, 4, 5) an xy plane is (3, 4, 0) [i.e z-coordinate is zero].

Hence, the correct answer is option D.
