According to Newton's law of gravitation, gravitational force between two objects of mass m1,m2, located at distance R between each other is F=R2Gm1m2, where G=6.674⋅10−11m3kg−1s−2 is the universal gravitational constant.
Using the last formula, the distance between the cannonball and marble is:R=FGm1m2=0.48⋅10−10N6.67⋅10−11m3kg−1s2⋅20kg⋅0.01kg≈0.53m
