उत्तर
Mass of the earth (M) = 6 × 1024 kg
Mass of the Sun (m) = 2 × 1030 kg
G Universal constant = 6.67 × 1011 Nm2/kg2
The average distance between the two d = 1.5 × 1011 m.
F = `G xx (M_exxm_s)/r^2`
F = `(6.67 xx 10^-11 Nm^2 kg^-2xx (6 xx 10^24 xx 2 xx 10^30))/(1.5 xx 10^11m)^2`
F = 3.57 × 1022 N
Gravitational force between the earth and the sun = 3.57 × 1022 N
