Electromagnetic and strong force
I have heard that the strong nuclear force is stronger then the electromagnetic force at short ranges, "Up to two and a half times the proton diameter". Ok, so i have an approximation of the length it dominates over the electromagnetic force, but i don't know where the force starts from; is it at the center of the proton, or is it from the edge? And why does my source say "up to" and not exactly? Why is this length only an approximation??

Protons and neutrons are made of quarks, which are point particles. The strong force is a force between quarks.

The "strong force" between nucleons (protons and neutrons) is a sort of "residual effect" from the interactions among the quarks that they're composed of. It's analogous to the van der Waals force between atoms and molecules, which is a residual effect of the electromagnetic forces among the nuciel and electrons that they're composed of.

What does residual mean?
