Two objects of mass 1.00 × 103 kg each are a distance of 4.00 m from each other. If the center of one mass is regarded as being at the origin of the x-axis, and the other is centered at 4.00 m along the x-axis, what is the magnitude of the gravitational field of the two masses combined at 8.00 m along the positive x-axis? Each gravitational field acts independently. Use a free body diagram and add the vectors.
