If an electron is exactly located at region r, it is natural for trope theorists to hold that the electron's mass trope and charge trope are also exactly located at r.

To see why, let e be an electron, and suppose that it instantiates two different universals: a mass universal, um, and a charge universal, uc. Suppose that e is exactly located at region r. Then it will be natural for the immanent realist to say that (i) um is exactly located at r as well, or at least at some region rm that has r as a part, and (ii) uc is exactly located at r or at some region rc that has r as a part. (If these universals are also instantiated elsewhere, then it will be debatabl
