Final answer:
The 10 N force would do the most work if all forces act over the same distance, as work is calculated as the product of force and distance.
Step-by-step explanation:
The force that does the most work is determined by the equation for work, which is work = force × distance. If the distance is the same for all forces, then the force with the greatest magnitude will do the most work. Therefore, without additional information, specifically the distance over which each force acts, the 10 N force would do the most work assuming all other conditions are equal.
