Calculate the force of gravitation between the earth and the sun, given that the mass of earth = 6 × 1024 kg. and of the sun = 2 × 1030 kg. The average distance between the two is 1.5 × 1011 m.
Mass of the earth Me = 6 × 1024 kg
Mass of the sum Ms = 2 × 1030 kg
The average distance between the two (r) = 1.5 × 1011
∴ Gravitational force (f ) = G mems / R2
f = (6.67 x 10-11 x 6 x 1024 x 2 x 1030) / (1.5 x 1011)2
f = 3.56 × 1022 N
