The gravitational force of attraction between Earth and the Sun

is 3.52 x 1022 newtons. Calculate the mass of the Sun. [Show all

2.0 * 10^ 30 kg

Explanation:

here constants used will be mass of earth which is 6 * 10 ^ 24 kg

distance between earth and sun is 1.50 * 10 ^ 11 m

G = 6.67 * 10 ^ - 13 N m^2 / kg^2

formula is F = G m1 m2 / r^2 where F is gravitational force, G is universal gravitational constant, m1 is mass of Sun, m2 is mass of earth, r is distance between earth and sun

making m1 as subject matter we get

m1 = (F r^2) / (G m2)

m1 = {3.52 * 10 ^22 N * (1.50 * 10 ^ 11 m) ^2 } / (6.67 * 10 ^ - 13 N m^2 / kg ^2 * 6 * 10 ^24 kg)

m1 = (3.52 * 10 ^22 * 2.25 * 10 ^22) / (4.002 * 10 ^14) kg

m1 = 1.979 * 10 ^ 30 kg

m1 = 2.0 * 10 ^ 30 kg
