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 10^{24} kg, radius of earth = 6.4 x 10^{6} m and G = 6.67 x 10^{-11} N - m^{2}kg^{-2})

(a) \(\frac{1}{24\,\times\,10^{-24}}\)

(b) 24 x 10^{24}

(c) 24 x 10^{-24}

(d) \(\frac{1}{24\,\times\,10^{24}}\)
