Hello,
Can anyone help me with this flowchart? I'm using it as a study

The nucleus of an atom consists of protons and neutrons (no electrons). A nucleus of a carbon-12 isotope contains six protons and six neutrons, while a nitrogen-14 nucleus comprises seven protons and seven neutrons. You perform a nuclear physics experiment in which you bombard nitrogen-14 nuclei with very high speed carbon-12 nuclei emerging from a particle accelerator. As a result of each such collision, the two nuclei disintegrate completely and a mix of different particles are emitted, including electrons, protons,...

5) A nucleus of Uranium-238 may be considered to contain 92 positively charged protons and 146 neutrons of the same mass as the protons, but no charge. Assuming that the volume of the nucleus is 238 times that of a proton, and the proton to be a sphere of radius 1.2 x 10^-15m, what is the strength of the electric field at the surface of the nucleus?
