In an inertial frame of reference, a series of experiments is conducted. In each experiment, two or three forces are applied to an object. The magnitudes of these forces are given. No other forces are acting on the object. In which cases may the object possibly remain at rest? The forces applied are as follows: 2 N; 2 N 200 N; 200 N 200 N; 201 N 2 N; 2 N; 4 N 2 N; 2 N; 2 N 2 N; 2 N; 3 N 2 N; 2 N; 5 N 200 N; 200 N; 5 N I figured that A and B and C were the only ones possible since the net force could add up to 0 but it says I'm wrong... I think there is some conscept I am missing help?
