Question

The coordinates of the foot of perpendicular drawn from the point (2,5,7) on the X-axis are given by (A) (2,0,0) (B) (0,5,0) (C) (0,0,7) (D) (0,5,7)

Since, the foot of the perpendicular lie on X-axis. So, it is of the form

(a, 0, 0)

. The coordinates of the point where the perpendicular has to be drawn are

(2, 5, 7)

.

∴ a = 2

Hence, the required point is

(2, 0, 0)

.
