During calibration, two actuators push a sensor mount with equal-sized forces. In one setting, the directions of the forces are 120° apart; in a second setting, they are 60° apart. The actuators apply the same force in both settings. Which statement correctly compares the resultant forces in the two settings?
The resultant force is larger at 60° than at 120°.
The resultant force is the same at 60° and at 120°.
The resultant force is smaller at 60° than at 120°.
The resultant force is zero at 120° but not at 60°.
