F = × 10^ N

The approximate mass of Earth is kg. The sun’s mass is approximately kg. They are approximately m apart. Use the equation to compute the gravitational force, F, between them. (Remember, ).

Substitute these values in the combined variation equation F = G m1m2 d2 Then, solve for G: × 10^ N m2 kg2
