Indeed. To get even geekier, the tension in the string would not be zero
because of tidal effects: the top ball experiences a lower acceleration
due to the quadrapole nature of the tidal field. Seen from the
center of mass of the system, the top mass is actually accelerating
away (upwards). But obviously this is way beyond what the designers
of the test intended.
