SSC MTS EXAM

Detailed explanation-1: -There are three subatomic particles: protons, neutrons and electrons. Two of the subatomic particles have electrical charges: protons have a positive charge while electrons have a negative charge. Neutrons, on the other hand, don’t have a charge.

Detailed explanation-2: -On the atomic level, protons are positively charged and electrons are negatively charged.

Detailed explanation-3: -Protons contain two up quarks and one down quark. Neutrons contain one up quark and two down quarks. The nucleus is held together by the “strong nuclear force, ‘’ which is one of four fundamental fources (gravity and electromagnetism are two others).

Detailed explanation-4: -A proton has positive charge of 1, that is, equal but opposite to the charge of an electron. A neutron, like the name implies, is neutral with no net charge. The charge is believed to be from the charge of the quarks that make up the nucleons (protons and neutrons).
