Question

An apple of mass 100 g falls from a tree because of gravitational attraction between the earth and the apple. If the magnitude of force exerted by the earth on the apple be F₁ and the magnitude for force exerted by the apple on the earth be F₂, then :

(a) F₁is very much greater than F₂
(b) F₂ is very much greater than F₁
(c) F₁ is only a little grater than F₂
(d) F₁ and F₂ are exactly equal

Open in App

Solution

(d) F₁ and F₂ are exactly equal in magnitude
According to Newton's third law of motion, if an object exerts a force on another object, then the second object exerts an equal and opposite force on the first object.
