The force of attraction , f of a body varies directly as its mass m and inversely as the square of the distance d from the body. when m=8 kilograms and d=5 meters , f =100 newtons. find f when m=2 kilograms and d = 15 meters.

    EQUATION: F = km/d²

    (100) = k (8)/(5)²

    100 = k (8/25)

    100 ÷ 8/25 = k 8/25 ÷ 8/25

    312.5 = k

    f = (312.5)(2)/(15)²

    f = 625/225

    f = 2.78

    ANSWER: f = 2.78
