How does a particle with positive charge know that the particle its closing in to also has a positive charge and repels?

So, when charges are the same, there is a repulsion force. Or there is attraction force if both have opposite charges. But how does a positive charge know whether another charge is positive or negative for attraction or repulsion force?

    every charge produces an electric field around it and that field has a polarity. So another charge encounters the field and that causes the second charge to have a force towards or away from the first.

    A charged particle creates an electric field around it. The other particle responds to this electric field.

    In quantum electrodynamics, the charges exchange virtual photons.

    A neutral particle whispers in it's ear.

    To anthropomorphise.... it “feels” it.

    In reality, of course, there is no conscious activity and everything is driven by whatever the forces are and the particles move accordingly.
