Question

L is the foot of the perpendicular drawn from a point (3, 4, 5) on x-axis. The coordinates of L are
(a) (3, 0, 0)
(b) (0, 4, 0)
(c) (0, 0, 5)
(d) none of these

Answer 1

Let L be the foot of the perpendicular drawn from (3, 4, 5) an x-axis.
Since on x-axis, coordinates of y and z are zero.
$\therefore$ coordinates of L are (3, 0, 0)

Hence, the correct answer is option A.
