Final answer:
The net force when two people pull on a rope depends on the direction and magnitude of their forces.
Step-by-step explanation:
The net force when two people pull on a rope can be determined by summing the forces they exert on the rope. If the two people are pulling in the same direction, the net force is the sum of their individual forces. For example, if person A pulls with a force of 100 N and person B pulls with a force of 80 N, the net force is 180 N.
If the two people are pulling in opposite directions, the net force is the difference between their forces. For example, if person A pulls with a force of 100 N to the right and person B pulls with a force of 80 N to the left, the net force is 20 N to the right.
