Question

Massless particles are not only neutral, they are chargeless (unlike the neutron). Why is this so?

a) Neutrality due to equal numbers of protons and electrons
b) Chargeless nature due to lack of charged constituents
c) Massless particles can't carry charge
d) Massless particles always exist in neutral pairs

Answer 1

Massless particles, such as photons, are neutral and chargeless because they do not have any charged constituents.

Step-by-step explanation:

Massless particles, such as photons, are neutral and chargeless because they do not have any charged constituents. They do not have protons, electrons, or any other particles that carry an electric charge. For example, photons are elementary particles that have zero charge and are made up of a combination of electric and magnetic fields. Since they do not have any charged particles, they do not carry any electrical charge.
