The straight line `(x-3)/3=(y-2)/1=(z-1)/0` is Parallel to x-axis Parallel to the y-axis Parallel to the z-axis Perpendicular to the z-axis

A

(A) Parallel to x-axis

B

(B) Parallel to the y-axis

C

(C) Parallel to the z-axis

D

(D) Perpendicular to the z-axis

Text Solution

Verified by Experts

The correct Answer is:
(D) Perpendicular to the z-axis
The line is along the vector `3hati+hatj` which is perpendicular to the z-axis as `(3hati+hatj)*hatk=0`.
