Question

according to Newton's law of gravitation the apple and the earth experience equal and opposite force due to gravitation but it is the Apple that Falls towards the earth not the vice versa why

Answer 1

According to Newton's third law of motion, the force with which the earth is attracted towards the apple is equal to the force with which earth attracts the apple. However, the mass of the earth is extremely large as compared to that of apple. So acceleration of the earth is very small and is not noticeable.
