Two objects one of m=20,000kg and another of 12,500kg, are placed at a distance of 5 meters apart. what is the force of gravitation between these two objects

Forces of gravity between two objects =

G · (mass₁) · (mass₂) / (distance between them)²

G = 6.67 x 10⁻¹¹ m³ / kg · s²

So the gravitational forces (one in each direction) are

Forces = (6.67 x 10⁻¹¹ m³/kg·s²) · (20,000 kg) · (12,500 kg) / (5 m)²

Forces = (6.67x10⁻¹¹ · 2x10⁴ · 1.25x10⁴)/(25) · (m³·kg·kg/m²·kg·s²)

Forces = (6.67 · 2 · 1.25 x 10⁻³ / 25) · (kg·m/s²)

Forces = (6.67 x 10⁻⁴) · (kg·m/s²)

Forces = 0.0001667 Newton   (about 0.0024 ounce)

Note: The gravitational force acts between the centers of the objects, and that's where the "distance between them" is measured.  For two masses of 20,000 kg and 12,500 kg, there's a chance that you might not even be able to get their centers with 5 meters of each other, even if they're made of concrete or steel.  If not, then the gravitational forces between them would be less than 0.0024 ounce.)

force is mass*acceleration.

we have a very small mass: 11.4*0.001 kg

if we want 0.035n of force, we need an acceleration:

0.035 = 11.4*0.001*a

a = 0.035/(11.4*0.001) m/s^2
