As shown in the figure, three force vectors act on an object. The magnitudes of the forces as shown in the figure are F, = 80.0 N, F2 = 60.0 N, and Fs = 40.0 N, where N is the standard Sl unit of force. The resultant force acting on the object is given by 30° O 60.0 N at an angle 90.0° with respect to +x-axis. O 35.5 N at an angle 34.3° with respect to +x-axis. O 20.0 N at an angle 34.3° with respect to +x-axis. O 40.0 N at an angle 60.0° with respect to +x-axis. O 180 N at an angle 60.0° with respect to +x-axis.
