Question

An apple falls from a tree because of gravitational attraction between the earth and apple. If F1 is the magnitude of force exerted by the earth on the apple and F2 is the magnitude of force exerted by apple on earth, then
(a)	F1 is very much greater than F2
(b)	F2 is very much greater than F1
(c)	F1 is only a little greater than F2
F1 and F2 are equal

Accepted Answer

Soln:

Answer is (d) F1 and F2 are equal
Explanation:
Netwon&rsquo;s third law of motion states that for every action there is equal and opposite reaction. Hence F1 and F2 are equal.
