In this scenario, the man exerts a downward force of 100 N on the chair. Simultaneously, the spring exerts an upward force of 150 N on the chair.
Since the man is sitting on the chair, according to Newton's third law of motion, the chair exerts an equal and opposite force of 100 N upward on the man. This force is known as the normal force.
The net force acting on the chair can be calculated by summing up the forces acting on it. In this case, the net force is the difference between the spring force and the man's force:
Net force = upward spring force - downward force exerted by the man
Net force = 150 N - 100 N
Net force = 50 N (upward)
Therefore, the net force acting on the chair is 50 N upward.
