The gravitational force between 2 objects is G (M₁ x M₂) / R²
G = 6.67 x 10⁻¹¹ Nt-m² / kg²
M₁ = 70 kg
M₂ = 6 x 10³ kg
R = 10
Force = (6.67 x 10⁻¹¹) (70) (6 x 10³) / (10)² = 2.8014 x 10⁻⁷ newton
The forces on the astronaut and on the module are equal.
That's the 'weight' of each one, in the presence of the other one.
(It's almost exactly 1 micro-ounce.)
Acceleration: F = M A ===> A = F / M
Of the astronaut:
A = (2.8014 x 10⁻⁷) / 70 = 0.000 000 004 002 m/s² (4.002 x 10⁻⁹ m/s²)
Of the command module:
A = (2.8014 x 10⁻⁷) / 6,000 = 0.000 000 000 04 669 m/s² (4.669 x 10⁻¹¹ m/s²)
