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
