MCQ

A normal to the plane x = 2 is:

A
< br > (0, 1, 1) < br >
B
< br > (2, 0, 2) < br >
C
< br > (1, 0, 0) < br >
D
< br > (0, 1, 0) < br >

✓

Answer

< br > (0, 1, 1) < br >

Solution:

The plane x = 2 is perpendicular to x axis So the angle is $\frac{\pi}{2},\cos\frac{\pi}{2}=0$

0 The plane x = 2 is parallel to both y axis and z axis So the angle is (0, 1, 1)
