Question

The mass of the Sun is 2 x 10 30 kg and that of the Earth is 6 x 10 24 kg. If the average distance between the Sun and the Earth is 1.5 x 10 11 m, calculate the force exerted by the Sun on the Earth and also by Earth on the Sun.

Answer 1

Answer:

3.57x10^22 N

Explanation:

M(Mass of the sun) = 2x10^30 kg

m(Mass of the earth) = 6x10^24kg

distance (r) = 1.5x10^11 m

F = GMm/r^2

F = (6.7x10^-11 x 2x10^30 x 6x10^24)/(1.5x10^11)^2

F = 3.57x10^22 N
