Neutron question

Given that they are made of separated fractionally charged quarks, shouldn't they ever so slightly tend towards the direction of an em field,. ie on a sphere earth we are closer to the surface charge opposed to the ionosphere and end up with a weak gravity? The average proton cancels the average electron. I must be missing something, i'm very much a non-scientist but just a consumer of information.

i guess i should rephrase that, after a quick glance through Thornhill's gravity the concept is nothing new to you guys,. rather the quarks being standard model, seem to require an argument against it to preclude a logical reasoning. Is there one?
