Problem

A particle is acted upon by two forces: F⃗1=40 N\vec F_{1}=40\,\text{N} due south and F⃗2=25 N\vec F_{2}=25\,\text{N} directed 30∘30^{\circ} west of north. Determine the magnitude and direction of the third force F⃗3\vec F_{3} that must be applied so that the particle remains in equilibrium.
