The mass of sun is 2 × 1030 kg and the mass of earth is 6×1024 kg. If the average distance between the sun and the earth be 1.5×108 km, calculate the force of gravitation between them.

Distance d=1.5 x 108km = 1.5 x 1011 m

Mass of the sun, m=2× 1030 kg


Mass of the earth, M = 6 * 1024 kg


Force of gravitation, F = G * m * M/d2


= 6.67 * 10-11 * 2 * 1030 * 6 * 1024/ (1.5 * 1011)2


= 6.7 * 12* 1021/ 1.5 * 1.5


F = 3.57 * 1022 N
