Question

There is an attractive force between all objects. Do you feel yourself gravitating towards massive buildings in our vicinity? I believe the force is negligible because it's so weak, is that correct?

Answer 1

Yes
F =G•m1•m2/R²
the gravitational constant G =6.67•10⁻¹¹ N•m²/kg² (!!!!)

Answer 2

never do your work
