In the same horizontal plane, there are three forces acting on a point, which are just balanced. It is known that the included angle of F1 and F2 is 90, the included angle of F2 and F3 is 120, and the ratio of the three forces is 0
F1 and F2 can be regarded as X and Y axes, and F3 can be decomposed into x and Y axes,
On the x-axis, which is the reverse direction of F1, there is F3 with √ 3 / 2
The y-axis, the opposite of F2, has half of F3
So F1: F2: F3 = √ 3 / 2:1 / 2:1
