X-coordinate of the center of mass:
Let x be the distance between the object mass and the tiny mass.
The center of gravity of an irregular object of mass 5.10 g is shown in the figure.
You need to move the center of gravity 2.30 cm to the left by gluing on a tiny 1.60-g mass, which will then be considered as part of the object.
Where should you attach this additional mass?
