Question:

What is the value of teta and cos teta when the force and the displacement is perpendicular to each other?

Answer:

The word perpendicular describes the relationship between two vectors which intersect at a right angle. Therefore:

$$\theta = 90{}^{\circ}$$

And $\cos(90{}^{\circ})$ equals 0:

$$\cos \theta = \cos (90{}^{\circ}) = 0$$

Answer: $\theta = 90{}^{\circ}, \cos \theta = 0$
