Question

Find the magnitude of the gravitational force between the Sun and the earth. (Mass of the Sun = 2 × 10²⁴ kg, mass of the earth = 6 × 10²⁴ kg and the distance between the centres of the Sun and the earth 1.5 × 10¹¹ m,

G = 6.67 × 10^-11 N.m²/kg²)

Answer 1

Data : m₁ = 2 × 10³⁰ kg,

m₂ = 6 × 10²⁴ kg, r = 1.5 × 10¹¹ m,

G = 6.67 × 10^-11 N.m²/kg², F =?

∴ F = 3.557 × 10²² N

The magnitude of the gravitational force between the Sun and the earth = 3.557 × 10²² N.
