the water drop could have collected some charge too, no? Also, r or 1/r^2 for closed orbit (eg. ellipse), but not being closed is not the same as unstable.
+ Coulomb's law --> orbit
Right but per the discussion with @gravity_levity we know that the potential of dipole induced forces go as 1/r^k k>2 where stability is impossible

And I’m not sure about the water drop collecting a net charge int the syringe, but yea I did neglect that
