  • 2. 

    Which quark has the strangest behavior?

    • Up quark

    • Down quark

    • Charm quark

    • Strange quark

    Correct Answer
    A. Strange quark
    Explanation
    The strange quark has the strangest behavior among quarks, which is why it is named as such. It decays more slowly than other quarks and leads to interesting particle interactions.

    Rate this question:

  • 3. 

    How many flavors of quarks exist in nature?

    • 2

    • 6

    • 4

    • 5

    Correct Answer
    A. 6
    Explanation
    In particle physics, there are six types, or flavors, of quarks: up, down, charm, strange, top, and bottom. These quarks differ from one another in their mass and charge characteristics.

    Rate this question:

  • 4. 

    What is the electric charge of an up quark?

    • 0

    • 1/3 e

    • 2/3 e

    • 1 e

    Correct Answer
    A. 2/3 e
    Explanation
    The electric charge of an up quark is 2/3​e, where e is the elementary charge. Quarks carry fractional electric charges, and the up quark is one of the two lightest quarks, along with the down quark. The down quark has an electric charge of −1/3e, and together, the up and down quarks combine to form protons and neutrons in atomic nuclei.

    Rate this question:

  • 5. 

    What type of particles are made up of quarks?

    • Leptons

    • Bosons

    • Fermions

    • Hadrons

    Correct Answer
    A. Hadrons
    Explanation
    Particles made up of quarks are known as hadrons. Hadrons include both mesons and baryons, and they are composite particles composed of quarks held together by the strong force mediated by gluons.

    Rate this question:

  • 6. 

    What type of hadron is composed of three quarks?

    • Baryon

    • Neutron

    • Lambda baryon

    • Pion

    Correct Answer
    A. Baryon
    Explanation
    A hadron composed of three quarks is called a baryon. Both the proton and the neutron are examples of baryons, as they consist of three quarks each. The proton is specifically composed of two up quarks and one down quark, while the neutron is made up of two down quarks and one up quark.

    Rate this question:

  • 7. 

    Which theory explains the strong interaction between quarks?

    • General relativity

    • Quantum chromodynamics

    • Electromagnetic theory

    • String theory

    Correct Answer
    A. Quantum chromodynamics
    Explanation
    The theory that explains the strong interaction between quarks is Quantum Chromodynamics (QCD). QCD is a branch of quantum field theory that describes the behavior of quarks and gluons, which are the elementary particles that make up protons, neutrons, and other particles known as hadrons.

    Rate this question:

  • 8. 

    Which quark has the highest mass?

    • Up quark

    • Down quark

    • Charm quark

    • Top quark

    Correct Answer
    A. Top quark
    Explanation
    The quark with the highest mass is the Top quark. The six known quark flavors, in order of increasing mass, are: up, down, charm, strange, top, and bottom. The top quark is significantly heavier than the other quarks, and its mass makes it a key focus of study in high-energy physics experiments.

    Rate this question:

  • 9. 

    Which flavor of quark is found in the neutron?

    • Up quark

    • Down quark

    • Charm quark

    • Top quark

    Correct Answer
    A. Down quark
    Explanation
    The flavor of quark found in the neutron is the down quark. Neutrons are composed of three quarks: one up quark and two down quarks. The combination of quarks in a neutron is (u,d,d), where (u) represents the up quark and (d) represents the down quark. This composition is one of the key aspects of understanding the structure of baryons like neutrons within the framework of the standard model of particle physics.

    Rate this question:

  • 10. 

    What is the mass of a down quark compared to an up quark?

    • The down quark is heavier.

    • The up quark is heavier.

    • They have the same mass.

    • Their masses cannot be compared.

    Correct Answer
    A. The down quark is heavier.
    Explanation
    The down quark is heavier than the up quark. The mass of an up quark is around approximately 2 MeV (Mega electron-volts), while the mass of a down quark is closer to 5 MeV.
