    Answer:

    ans: 1.26 × 10^(-6) N

    Explanation:

    suppose that;

    mass of Justhin ( m) = 74 kg

    mass of Christian (M) = 64 kg

    distance of separation (d) = 0.5 m

    universal gravitational constant(G) =6.67 × 10^(-11) Nm²/kg²

    so,

    gravitational force between them(F) = GmM/d²

    F = (6.67 × 74× 64)/ ( 10¹¹× 0.5²)

    = (1.26 × 10⁵)/ 10¹¹

    = 1.26 × 10^(-6) N
