What is the force of attraction a 50kg man and their 20kg dog if they are 1mm away from each other? Go to 5 decimals.

Answer 1

The equation you need is:

F_Gravity = Gm₁m₂/r²

G is the Gravitational Constant (6.6743 × 10-11 m3/kg s²) m₁ and m₂ are the masses and r is the distance between the objects. The 1 mm will need to be converted to 0.001 m, but the other numbers are in the correct units.

Plugging in those numbers you get 0.06674 Newtons.
