SSC MTS EXAM

Detailed explanation-1: -Protons and neutrons are composed of two types: up quarks and down quarks . Each up quark has a charge of +2/3. Each down quark has a charge of-1/3. The sum of the charges of quarks that make up a nuclear particle determines its electrical charge.

Detailed explanation-2: -Quarks are fundamental building blocks of matter. They are most commonly found inside protons and neutrons, the particles that make up the core of each atom in the universe. Based on current experimental evidence, quarks seem to be truly fundamental particles; they cannot be further subdivided.

Detailed explanation-3: -Protons and neutrons are made up of fundamental particles of matter called quarks.

Detailed explanation-4: -Protons and neutrons are not fundamental as they consist of sets of point-like particles called quarks held together by the exchange of messenger particles called gluons.
