The middle ball is at the center of mass in this case. That is obvious from the symmetry.
What its x-coordinate is depends upon what you choose for the origin of coordinates.
Three balls with masses of 4 g, 6 g, and 4 g,respectively, are connected by massless rods. The balls are located (in meter intervals).What is the x-coordinate of the center of mass?
