Yep, I know about unit vectors, but Thnx for the info. :)
Well, It's been solved in the book in Example, but I can't understand it...
I've drawn the following diagram to solve it. Am I doing it right? Also, 0° is for the parallel vectors ?
Homework Statement
Find the angle between two forces of equal magnitude when the magnitude of their resultant is also equal to the magnitude of either of the forces
2. The attempt at a solution
x-component of the resultant:
Rx = F1 cos 0\circ + F2 cos θ
Rx = F1 + F2 cos θ
It's...
