Final answer:
When a 5 N force pushes to the right and a 10 N force pushes to the left on a box, the net force is 5 N to the left, causing the box to move in that direction.
Step-by-step explanation:
When multiple forces act on an object, we need to consider their magnitude and direction to determine the overall effect on the object's motion. In this case, a 5 N force is pushing to the right, while a 10 N force is pushing to the left. To find the net force, we subtract the force on the left from the force on the right: 5 N - 10 N = -5 N.
The negative sign indicates that the net force is in the opposite direction of the 5 N force. Therefore, the box will be moved to the left by a net force of 5 N.
