Q33 of 50 Page 220

L is the foot of the perpendicular drawn from a point P (3, 4, 5) on the xy-plane. The coordinates of point L are

As L lies on xy plane, so its distance from xy plane is zero or we can say that z-coordinate is 0.


∵ L is perpendicular from P(3, 4, 5) to xy plane so its distance from yz and xz plane remains the same as that of point P


∴ Coordinates of L are (3, 4, 0)


∵ None of the option(A,B or C) matches with our answer.


Hence, Option(D) is the most suitable choice.
