Question

Which pair of concurrent forces could produce a resultant force having a magnitude of 15.Newtons?

Answer 1

2) 10. N. 30. N.

Step-by-step explanation:

Since you need to take into account the direction too, you need to make sure that the concurrent forces of the pair have to be equal or superior to the magnitude needed in both directions.

If the forces are in the same direction: 10 N + 30 N = 40 N > 15 N : OK!

If the froces are in oposite directions: - 10 N + 30 N = 20 N > 15 N : OK!
