1 Three forces are applied to an object, as indicated in the drawing. Force F has a magnitude of 20.0 newtons (20.0 N) and is directed 30.0 to the left of the +y axis. Force F2 has a magnitude of 17.0 N and points along the +x axis. What must be the magnitude and direction (specified by the angle in the drawing) of the third force F3 such that the vector sum of the three forces is 0 N? magnitude 18.68 N x Fy +y 30.0% F2 +x
