Question about gravity

Hello Rabbi, this time I address you as Dr.
I haven't had a chance to see and check if the following theory has been tested:
If, according to the theory, two charged particles exert a force on each other (attraction or repulsion, depending on the sign), is what we call the force of attraction actually the action of the charges on each other, and since everything is full of charges, the attraction of the body with the most charges is stronger?

Of course, I'm already raising the question: Why would attraction be greater than repulsion? Apparently there is the same amount of charge, but at most something else is missing to explain it?
