Question

One of the rectangular components of a force of 40 n is 20 n. find the angle it makea with this component

Answer 1

Given that one of the rectangular components of a force of 40 N is 20 N.

The relation between the 40 N force and the 20 N component can be given by the cosine of the angle between them.

Let the angle be θ, so,

cos θ = 20 / 40

cos θ = 1 / 2

=> θ = 60°

Hence 60° is the answer.
