If the point P lies on z-axis, then coordinates of P are of the form ________.

(0,0,z)

Explanation:


∵ P lies on z-axis and this axis is common to xz and yz planes or we can say that it lies on xz and yz planes.


∴ its y and x coordinates are going to be 0 but still it may have any distance form xy axis as it is ⊥ to it.


∴ Co-ordinates of P are of the form (0, 0, z)
