Three forces are applied to an object, as shown in the figure. Force F1 has a magnitude of 24.8 newtons (24.8 N) and is directed 30.0 to the left of the +y axis. Force F2 has a magnitude of 15.0 N and points along the +x axis. What must be the (a) magnitude and (b) direction (specified by the angle in the drawing) of the third force F3 such that the vector sum of the three forces is ON? +y' 30.0 (a) Number 21.62 Units N at + +h (b) Number Units N +1
