ELI5: Why electrons do not interact/get affected with strong force?
gpt
The four elementary forces can each only interact with particles that have particular properties. The gravitational force works on objects that have mass (it should work on individual particles with mass but we mostly see it on big objects because the force isn't that strong). The electomagnetic force works on anything with an electric charge. The strong nuclear force works on anything with a "color charge". Finally, the weak nuclear force works on anything with a "weak isospin".

Electrons have mass, charge, and weak isospin, but no color charge. Thus they will be affected by the gravitational, electromagnetic, and weak nuclear forces, but not the strong nuclear force. In the same vein, neutrons have no charge, so they won't be affected by the electromagnetic force.

So far the only particles with color charge we know of are quarks, and they are classified as "red", "blue", and "green" just like electric charges can be positive or negative. There's also "anti-red", "anti-blue", and "anti-green" for antiparticles. Just like positive and negative charges attract each other, color charges like to be neutral, either sticking together a color and it's anti-color for two particle systems, or all three colors together in three particle systems.
