A coordinate system (in meters) is constructed on the surface of a pool table, and three objects are placed on the table as follows: a m1 = 1.6-kg object at the origin of the coordinate system, a m2 = 2.9-kg object at (0, 2.0), and a m3 = 4.6-kg object at (4.0, 0). Find the resultant gravitational force exerted by the other two objects on the object at the origin. magnitude Incorrect: Your answer is incorrect. Your response differs significantly...
