### Physics: Forces and Equilibrium

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:

#### Check all that apply.

- 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

#### Explanation:
In physics, an object remains at rest if the net force acting on it is zero. This situation is known as equilibrium. The net force is the vector sum of all the forces applied to the object. If forces are balanced, the object will not experience any change in motion.

When checking for equilibrium, consider the magnitudes and directions of the applied forces. If the sum of the forces results in zero, the object will remain at rest. In the list above, you would check the options to see if they can sum up to zero either by straightforward addition or vector analysis.

The correct combinations where the net force can possibly be zero:
- \( 2 \, \text{N}; 2 \, \text{N} \)
- \( 200 \, \text{N}; 200 \, \text{N} \)

These cases indicate that the forces are capable of balancing each other out, thus keeping the object at rest. Other options will not sum to zero and therefore the object would not remain stationary.
