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)
