Question

How far apart are a 900kg car and an 80kg man if they experienced a gravitational attraction of 1 N?

Answer 1

The answer would be 2.2 millimeters because although this is basically impossible, you would use the formulas: F = G M₁ M₂ / R²

G = 6.67 x 10⁻¹¹ m³ / kg - s² to figure out your answer so it would look like this:

(6.67 x 10⁻¹¹) (900) (80) / R²

(6.67 x 10⁻¹¹ x 900 x 80)

4.8 x 10⁻⁶

√(4.8 x 10⁻⁶)

0.0022 meter

2.2 millimeters

Hope this helps :)
