An apple of mass 100 g falls from a tree because of gravitational attraction between the earth and the apple. If the magnitude of the force exerted by the earth on the apple be $F_1$ and the magnitude of the force exerted by the apple on the earth be $F_2$, then:
(a) $F_1$ is very much greater than $F_2$
(b) $F_2$ is very much greater than $F_1$
(c) $F_1$ is only a little greater than $F_2$
(d) $F_1$ and $F_2$ are exactly equal

According to Newton's third law of motion, if an object exerts a force on another object, then the other object also exerts a force to the first object in exact equal magnitude and opposite direction.

So, the force $(F_1)$ exerted by the earth on the apple is exactly equal to the force$(F_2)$ exerted by the apple on the earth.

Therefore, option (d) is correct.
