ANSWER:Solution Step 1 of 2 yes, According to newton’s third law, for every action there is a reaction force which is equal in magnitude but opposite in direction. Here when we fall from certain height on the earth surface; since both the earth has mass M and a person has mass m. As they have masses,they are acted by an attraction force between them called gravitational force; which is directly proportional to the product of masses and inversely proportional to square of the distance(r). GMm That is F G r2 Where G is universal gravitational constant. F ep= F pe= F G Where F epis the force of earth on person called weight, peis the force of person on earth and F Gs gravitational force.
