Question
An apple falls from a tree because of gravitational attraction between the earth and the apple. If F1 is the magnitude of the force exerted by the earth on the apple and F2 is the magnitude of the force exerted by the apple on earth, then
Options
F1 is very much greater than F2
F2 is very much greater than F1
F1 is only a little greater than F2
F1 and F2 are equal
Solution
F1 and F2 are equal
Explanation:
F1 and F2 are equal as Newton’s law of gravitation obey Newton’s third law of motion, i.e., if an object exerts a force on another object, then the second object exerts an equal and opposite force on the first object.
