Two spherical masses m1 = 4.10 g and m2 = 3.90 g are located at coordinates (-5.00, -3.75) cm and (-3.00, 4.00) cm, respectively. (a) What is the gravitational field at the origin? Express your answer in vector form. m/s2 (b) What is the force experienced by a mass m3 = 8.00 g placed at the origin? Express your %3D answer in vector form. Fnet, g =. ------_ N (c) What is the gravitational potential energy of the three-mass system?
