Problem 13.12: Calculate center of mass

Please wait for the animation to completely load.

Four spheres are shown in the animation. A blue sphere is half as massive as a red one, and a purple sphere is twice as massive as a red one. Where should the purple one be placed in order for the center of gravity to be at the location of the black dot (position is given in meters)? Restart.
