Q. 7

An apple falls from a tree. An insect in the apple finds that the earth is falling towards it with an acceleration g. Who exerts the force needed to accelerate the earth with this acceleration g?

Answer :

From Newton’s third law, the force felt by both the objects are equal in magnitude but opposite in direction. Hence, the earth also experiences the same force as the apple. But as it has larger mass we do not see the earth accelerate towards apple.
