Particle A orbits the nucleus, and Particle B is located in the nucleus.
Explanation:
The atoms consists of three types of particle:
- Proton: it is located in the nucleus of the atom, its mass is approximately [tex]1.67\cdot 10^{-27}kg[/tex], and its charge is [tex]+e=1.6\cdot 10^{-19}C[/tex] (positive charge)
- Neutron: it is also located in the nucleus of the atom, its mass is similar to that of the proton, and it has no electric charge
- Electron: it orbits around the nucleus, it is much lighter than the proton and the neutron (mass: [tex]9.11\cdot 10^{-31}kg[/tex]), and it is negatively charged ([tex]q=-e=-1.6\cdot 10^{-19}C[/tex])
Looking at the definitions above, and since we know that particle A has very little mass in comparison to particle B (so, particle A must be an electron), we can only conclude the following:
Particle A orbits the nucleus, and Particle B is located in the nucleus.
In fact, we cannot determine whether particle B is a proton or a neutron, since we don't know anything about its charge.

Answer: the correct answer would be Particle A orbits the nucleus, and Particle B is located in the nucleus. I think Particle A represents the electrons while B represents protons and neutrons.
