A pair of objects have the same diameter, but one is made of much denser material and has more mass. Where is the barycenter, and what motion follows?
A
Closer to the less dense object because it is easier to move; that object has the smaller wobble.
B
Closer to the denser, more massive object; that object has the smaller wobble.
C
At the surface of the denser object because density replaces the need for orbital motion.
D
Exactly halfway between them because their diameters match; both wobbles are equal.
