The weight of a brick lying on the Earth is 50 N. With what force is the Earth attracted to a brick during its free fall?

According to Newton’s third law, the Earth is attracted to a brick with the same modulus of force with which a brick is attracted to the Earth. In free fall, the force of attraction of the brick to the Earth is equal to its weight, hence the force with which the Earth is attracted to the brick is also equal to the weight of the brick. That is, F = 50H.
