Two balls, one of gold with a mass of 100 kg and one of wood with a mass of 1 kg, are suspended 1 meter apart. What is the attractive force, in newtons, of
a. the gold ball acting on the wooden ball?
b. the wooden ball acting on the gold ball?

    F =G•m₁•m₂/R²
    the gravitational constant G =6.67•10⁻¹¹ N•m²/kg²,
    F₁=F₂ = G•m₁•m₂/R²=
    =6.67•10⁻¹¹•1•100/1²=6.67•10⁻ ⁹ N.
