Question

The mass of the earth is 6 × 10²⁴ kg. The distance between the earth and the Sun is 1.5 × 10¹¹ m. If the gravitational force between the two is 3.5 × 10²² N, what is the mass of the Sun? (Use G = 6.7 × 10^-11 N.m² kg^-2)

Answer 1

Data : m₁ = 6 × 10²⁴ kg,

r = 1.5 × 10¹¹ m, F = 3.5 × 10²² N,

G = 6.7 × 10^-11 N.m² kg^-2, m₂ = ?

= 1.96 × 10³⁰ kg (mass of the sun)
