Answer 1

To determine which change in force would stop the box from moving, we need to consider the net force acting on it.

- If a force is pulling to the right and we need to stop the box from moving, we can either reduce that force or apply an equal and opposite force.
- If there is a force acting to the right, subtracting a force pulling to the left would not stop the box from moving to the right; it would actually reduce the opposing force but not stop the motion.

1. **Subtracting 8 N of force pulling to the left:** This would further increase the net rightward force, making it more likely to move right.

2. **Subtracting 8 N of force pulling to the right:** This reduces the rightward force, which may help to bring the system toward equilibrium if there’s also a leftward force present.

3. **Adding 6 N of force pulling to the right:** This adds more force to the right and would increase motion to the right.

4. **Adding 6 N of force pulling to the left:** This would create more force opposing the rightward movement, which could potentially stop it, depending on the existing forces.

From all the options, **adding 6 N of force pulling to the left** is the only action that would help counteract any existing force to the right effectively and could potentially stop the box from moving.

So, the correct answer is: **adding 6 N of force pulling to the left.**
