    Answer:

    1.48×10⁻⁷ Newtons

    Explanation:

    From the question,

    According to newton’s law of universal gravitation.

    F = Gmm’/r²…………………… Equation 1

    F = gravitational force, G = gravitational constant, m = mass of the first ball, m’ = mass of the second ball, r = distance between the balls.

    Given: m = m’ = 8 kg, r = 17 cm = 0.17 m,

    Constant : G = 6.67×10⁻¹¹ Nm²/kg²

    Substitute these values into equation 1

    F =  (6.67×10⁻¹¹×8×8)/(0.17²)

    F = 1.48×10⁻⁷ N
