Calculate the force of gravitation between the earth and the Sun, given that the mass of the earth = 6 × 1024 kg and of the Sun = 2 × 1030 kg. The average distance between the two is 1.5 × 1011 m.

Given that

Mass of the sun ms = 2 × 1030 kg

Mass of the earth me = 6 × 1024 kg

Gravitation constant G = 6.67 x 10-11 N m2/ kg2

Average distance r = 1.5 × 1011 m

Find out

The force of gravitation between the earth and the Sun

Solution

Consider Universal law of Gravitation

F = G× m1 × m2/ r2

On substituting the values we get

=6.7×10−11×2×1030×6×1024/(1.5×1011)2

= 3.57 × 1022 N

Solution

 Hence, the force of gravitation between the Earth and the Sun is 3.57 × 1022 N
