Answer:
the magnitude of gravitational force is 6 x 10⁻⁸ N.
Explanation:
Given;
mass of the two people, m₁ and m₂ = 90 kg
distance between them, r = 3.0 m
The magnitude of gravitational force exerted by one person on another is calculated as;

where;
G is gravitational constant = 6.67 x 10⁻¹¹ Nm²/kg²

Therefore, the magnitude of gravitational force is 6 x 10⁻⁸ N.
