The reaction force that the fence exerts on the chair is equal in magnitude and opposite in direction to the force exerted by the chair on the fence. So, the reaction force is 8 N.
Answer: 8 N.
The reaction force that the fence exerts on the chair is equal in magnitude but opposite in direction to the force applied by the chair on the fence. Therefore, the reaction force exerted by the fence on the chair is 8 N.
To find the reaction force that the fence exerts on the lawn chair, we can use Newton's third law of motion, which states that every action has an equal and opposite reaction. In this case, the action is the chair being pushed into the fence by the wind with a force of 8 N.
Since the chair is not moving vertically, we can assume that the reaction force will also be equal to 8 N in the opposite direction. This is because when the chair pushes against the fence with a force of 8 N, the fence pushes back with an equal force of 8 N.
Therefore, the correct answer is 8 N
