    Answer:

    F = 7.8  10³ N

    Explanation:

    For this exercise we will use the law of universal Gravitational

             F = G M m / r²

    for initial conditions

            F₀ = G M m₀ / r₀²

             

          They tell us that the mass changed at m = 2m  distance at r = 0.8r₀

    we substitute

          F = G M 2m₀ / (0.8 r₀) ²

          F = (GM m₀/ r₀²)   \frac{2}{0.64}

          F = 3.125 F₀

         

    let’s calculate

          F = 3.125 2.5 10³

          F = 7.8125 10³ N
