Calculate the magnitude of the gravitational field of Pluto at the location of Neptune, in meters per square second, when they are 4.481012 m apart, as they are at present. The mass of Pluto is 1.401022 kg . Object 1 with m1 = 3.5 kg and Object 2 with m2 = 17.5 kg are separated by r = 0.34 m. Express the magnitude of the gravitational force F in terms of m1, m2, r, and the gravitational constant G
