Question

A 50 kg person and a 70 kg person are sitting on a bench close to each other about .5 m apart.

Estimate the magnitude of the gravitational force each exerts on the other.

Answer 1

1.0 x 10-6 N.

Step-by-step explanation:

The gravitational force

Fg = G m1 m2 / r2 = (6.673 x 10-11) (50 kg) (75 kg) / (0.50 m)2 = 1.0 x 10-6 N.
