From Newton's third law, "action and reaction and equal and opposite"

Hence the reactive force on the fence is 47.24N

Given Data

Mass of Lawn Chair = 4kg

Force of wind = 8N

Let us find the weight of the chair

Weight of Chair = 4*9.81 = 39.24N

The reactive force exerted by the fence on the chair is equal to the total force from the wind and the weight of the chair

Reactive force = Total Force = 39.24+8

Reactive force = Total Force = 47.24N

The reaction of the fence on the chair is 8N in the opposite direction.

What is force?

Force is that which causes motion. When force is applied to a body, the body moves a distance in the direction of the force.

We must note that from Newton's third law, action and reaction are equal and opposite. If the chair hits the fence with a force of 8N, it the follows that the reaction of the fence on the chair is also 8N in the opposite direction.
