The change in force that would stop the box from moving is subtracting 8 N of force pulling to the right.
To stop the box from moving, you need to apply a force in the opposite direction to the force acting on it. Therefore, if the box is being pulled to the left with a force of 6 N, you would need to apply a force pulling to the right of at least 6 N. So, the correct answer would be "adding 6 N of force pulling to the right".
To determine which change in force would stop the box from moving, we need to consider the net force acting on the box. The net force is the vector sum of all the forces acting on the box.
If the box is initially moving to the left, we can assume there is a force pushing or pulling it to the right, opposite to its motion. We will consider positive forces in the direction of motion and negative forces in the opposite direction.
Let's analyze each option to see their effect on the net force:
1. Adding 6 N of force pulling to the left: This would increase the force opposing the motion of the box. If the box is initially moving to the left and we add a force pulling to the left, it will further oppose the motion. Therefore, it would contribute to stopping the box from moving.
2. Adding 6 N of force pulling to the right: This would increase the force in the direction of motion. If the box is already moving to the left and we add a force pulling to the right, it would act in the same direction as the motion and increase the net force, which would not stop the box.
3. Subtracting 8 N of force pulling to the left: This would decrease the force opposing the motion of the box. If the box is initially moving to the left and we subtract a force pulling to the left, it would reduce the opposition to the motion and potentially increase the net force, which could keep the box moving. Therefore, it would not stop the box.
4. Subtracting 8 N of force pulling to the right: This would decrease the force in the direction of motion. If the box is already moving to the left and we subtract a force pulling to the right, it would act in the direction opposite to the motion and decrease the net force, potentially stopping the box from moving.
Based on our analysis, option 4 (subtracting 8 N of force pulling to the right) would be the change in force that could stop the box from moving.
