Rate this question:
The center of mass lies on the line joining the centers of each mass.
The center of mass is closer to the larger mass.
It is possible for the center of mass to lie within one of the objects.
If a uniform rod of mass m were to join the two masses, this would not alter the position of the center of mass of the system without the rod present.
Rate this question:
For a uniform symmetric object, the center of mass is at the center of symmetry.
For an object on the surface of the Earth, the center of gravity and the center of mass are the same point.
The center of mass of an object must lie within the object.
