An apple of mass 0.25 kg falls from a tree. The ratio of acceleration of the apple towards the earth and of the earth towards the apple is (mass of earth = 6 x 1024 kg, radius of earth = 6.4 x 106 m and G = 6.67 x 10-11 N - m2kg-2)

(a) $\frac{1}{24\,\times\,10^{-24}}$

(b) 24 x 1024

(c) 24 x 10-24

(d) $\frac{1}{24\,\times\,10^{24}}$
