Q. Consider the following statements:
1.Quarks are fundamental particles that make up protons and neutrons.
2.Quarks have the capability to exists independently.
Select the correct answer using the codes given below:
Answer: A
Notes:
Explanation –
Statements 1 is correct. Quarks are fundamental particles that make up protons and neutrons. They are considered elementary particles and are key components of the Standard Model of particle physics. Protons and neutrons are common examples of three-quark hadrons, which are composite particles made up of three quarks bound together by the strong nuclear force.
Statement 2 is incorrect. Quarks do not have the capability to exist independently. They are always bound together by the strong nuclear force within hadrons (e.g., protons and neutrons). The strong nuclear force prevents quarks from being observed in isolation, a phenomenon known as quark confinement.
