Question

Determine the gravitational force that you exert on another person 1.50 m away. assume that you and the other person are point masses of 70.0 kg each.

Answer 1

Given: Universal Gravitational constant = G = 6.67 x 10⁻¹¹ N m²/Kg²
 
 Mass₁ = 70 Kg;  Mass₂ = 70 Kg  Radius r = 1.5 m;    Force F = ?

Formula: F = Gm₁m₂/r²

F = (6.67 x 10⁻¹¹ N m²/Kg²)(70 Kg)(70 Kg)/(1.5 m)²

F = 1.45 X 10⁻⁷ N
