We use the formula: F = Gm1m2 / r^2: where F is the gravitational force, G is the gravitaional constant, 6.674 × 10^-11 N × m^2 / kg, m1 and m2 are the masses of the two objects and r is the distance between. Substituting the given values, we get: F = (6.674 × 10^-11)(450)(570) / (.750)^2 = 3.04 × 10^-5 N.
