Homework Answers
here,
mesons are hadronic subatomic particles composed of one quark and one antiquark,
bound together by the strong interaction.
Because mesons are composed of sub-particles,
they have a physical size,
with a diameter of roughly one fermi
therefore , A particle composed of a quark and an antiquark is classified as a b) Meson

Quarks carry spin 1/2. Two quarks (or actually a quark and an antiquark) bind together to make a meson (such as pion or kaon). Three quarks bind together to make a baryon (such as proton or neutron). Assume all quarks are in the ground state so the orbital angular momentum is zero). (1) What spins are possible for mesons? (2) What spins are possible for baryons?

In the quark model of fundamental particles, a proton is composed of three quarks: two "up" quarks, each having charge +2e/3, and one "down" quark, having charge -e/3. Suppose that the three quarks are equidistant from one another. Take the distance to be 1.48×10-15 m and calculate the potential energy of the subsystem of two "up" quarks. (MeV) Calculate the total electric potential energy of the three-particle system. (MeV)
