Hello.

> Is there any electromagnetic force of repulsion between two quarks?
> And, hypothetically speaking [as independent quarks are not observable], could there be EMF of attraction between an electron and an independent quark?

Actually, both the questions boil down to the following - am I correct in saying that EMF is "observable", "present" when the charges involved is e or more than that? That is, when one of the charges involved is a fractional e [as in the case of quark, 1/3e], there is no observable EMF or some other force dominates.

Let me know if I am correct or wrong.

Thanks

Since the quarks and the electrons are electrically charged, they can interact electromagnetically (at least in theory). The same can be said about quarks alone, or electrons alone. When quarks are involved, other <forces> (like the strong one mediated by the gluon field) dominate the e-m one, but that doesn't mean that the e-m one is not observable, or being not observable depends on whether the charge is under 1e or not.
