Three particles A, B, C with masses of 100 g, 200 g, and 300 g, respectively, are placed at the vertices of an equilateral triangular structure with a side length of 2 m. A is placed at the \( (0, 0) \) position and B is placed at \( (2, 0) \) position in a Cartesian coordinate system. Assume that \( \triangle ABC \) lies parallel to the base. The distance between the center of mass and the position of the particle A is ........... m. (rounded off to 2 decimals)
