An apple hanging on a branch is attracted to the Earth with a force equal to 3 N. With what force does an apple pull the Earth to itself?

In order to solve this problem, it is necessary to use Newton’s third law, according to which bodies act on each other with forces that are equal in magnitude, but opposite in their direction.
Therefore, an apple that hangs on a branch attracts the Earth to itself with exactly the same modulus of force with which it is attracted to the Earth, that is, equal to 3 * N.
Answer: an apple attracts the Earth to itself with a force equal to 3 * N.
