    Answer:

    8 units

    Explanation:

    From the question given above, the following data were obtained:

    Initial force (F₁) = 72 units

    Initial distance apart (r₁) = r

    Final distance apart (r₂) = tripled = 3r

    Final force (F₂) =.?

    The final force between the two objects can be obtained by using the following formula:

    F₁r₁² = F₂r₂²

    72 × r² = F₂ × (3r)²

    72r² = F₂ × 9r²

    Divide both side by 9r²

    F₂ = 72r² / 9r²

    F₂ = 8 units

    Therefore, the final force between the two objects is 8 units
