Question

The length of the perpendicular drawn from the point P (3, 4, 5) on y-axis is
(a) 10
(b) $\sqrt{34}$
(c) $\sqrt{113}$
(d) 512

Answer 1

The length of the perpendicular drawn from the point P (3, 4, 5) on y-axis is given by

$$\begin{gathered} \sqrt{3^2+5^2} \\ =\sqrt{34} \end{gathered}$$
Hence, the correct answer is option (b)
