An apple falls from a tree because of gravitational between the earth and apple. If `F_(1)` is the magnitude of force exerted by the earth on the apple and `F_(2)` is the magnitude of force exerted by apple on earth, 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 equal

Text Solution

Verified by Experts

The correct Answer is:
D
Newton's law of gravitation obeys Newton's 3rd law of motion i.e., forces of attraction between any two object ate equal and opposite. Hence `F_(1)` and `F_(2)` are equal.
