Forces of gravity between two masses = G M₁ M₂ / R²
G = universal gravitational constant = 6.67 x 10⁻¹¹ N-m² / kg²
F = (6.67 x 10⁻¹¹) (0.12) (0.20) / (0.75)²
F = 2.85 x 10⁻¹² Newton (about 0.000 000 000 01 ounce)
The gravitational forces are always the same in both directions.
(Your weight on the Earth is the same as the Earth's weight on you.)
