Calculate the gravitational pull between the Earth and the Moon

 F = 1.99 10²⁰ N

Explanation:

The gravitational attraction is given by the expression

         F =  

where G is the constant of attraction 6.67 10⁻¹¹ N m²/kg²

in this case the bodies are the Earth and the Moon

let's calculate

         F = .67 10⁻¹¹ 7.36 10 22 5.98 1024 / (3.84 108) 2

         F = 1.99 10²⁰ N
