Homework Statement
What particle(s) does the weak force affect? I think it's electrons but my teacher thought it was quarks since the range of the weak force is <0.003 fm.

The weak force is one of the four fundamental forces of nature and is responsible for the radioactive decay of particles. It affects particles by causing them to change into different types of particles, a process known as weak interaction. This force is responsible for the transformation of electrons into neutrinos and quarks into up and down quarks.
The weak force is different from other fundamental forces because it only affects particles at a very short range, about 10^-18 meters. It is also the only force that can change one type of particle into another. The other fundamental forces, such as gravity and electromagnetism, do not have this capability.
Unlike gravity and electromagnetism, the effects of the weak force are not easily observable in everyday life. It is only noticeable in the decay of radioactive particles, which can be observed in laboratory experiments or in certain natural phenomena.
The weak force was first theorized by physicists Enrico Fermi and Wolfgang Pauli in the 1930s. It was later confirmed through experiments in the 1950s and 1960s, including the discovery of the W and Z bosons, which are the particles responsible for mediating the weak force.
The weak force plays a crucial role in our understanding of the universe and the behavior of particles. Without it, elements heavier than hydrogen would not exist, as the weak force is responsible for the fusion of protons and neutrons in the nuclei of atoms. It also helps explain some of the mysteries of the early universe, such as the abundance of matter over antimatter.
