Consider the given mass distribution where the x and y-coordinates are provided in meters: 5.0 kg at (0.0, 0.0) m, 2.9 kg at (0.0, 4.4) m and 4.0 kg at (2.6, 0.0) m. Where must a fourth object of around 6.5 kg be positioned so that the center of gravity of the four-object arrangement will be at (0.0, 0.0) m?
