The earth attracts an apple. Does the apple also attract the earth? If it does, why does the earth not move towards the apple?

Answer:
According to Newton’s third law of motion, action and reaction are equal and opposite. It means that the force on the apple due to earth’s attraction is equal to that on the earth due to apple’s attraction. But we know, acceleration image
As the mass of the earth is very large as compared to that of the apple, the acceleration experienced by the earth will be so small that it will not be noticeable.
