Calculate the force between two objects that have masses of 70 kilograms and 2000 kilograms separated by a distance of 1 meter

Judging by the kind of information you gave, I'm guessing that
you're looking for the gravitational forces drawing these two
objects together.

Gravitational force:                 F = G  m₁ m₂ / R²

F = gravitational force, newtons
G = gravitational constant = 6.67 x 10⁻¹¹ newton-meter²/kg²
m₁ = mass of one object, kg
m₂ = mass of the other object, kg
R = distance between their centers, meters

Using the data given in the question . . .

      F = (6.67 x 10⁻¹¹ N-m²/kg²) (70 kg) (2000 kg) / (1 m)²

         = (6.67 x 10⁻¹¹  x  70  x  2000)  Newton

         =    9.338 x 10⁻⁶  Newton

           (about 0.000034 ounce)
