A force of 10N makes an angle of 30° with Y-axis. The magnitude of z-componentwill be

(a) 5N

(b) 8.66 N

(c) 10N

(d)0

SOLUTION :

The above force makes an angle of 30 ° with the y axis.

Hence the y component of the force is X cos 30 °

=> √3 / 2 X

Z about is Perpendicular to the y axis.

So, Z component :

Z component = √3 / 2 X × cos ( 90° )

Cos ( 90° ) = 0

Have the z component of this force is 0 Newton.

Hence, option D is the correct answer.
