Nuclear and particle physics

Two protons inside a beryllium-7 ( $47Be^{7}_{4}\text{Be}$ ) nucleus are separated by a distance of about $1.2 \times 10^{-15} \text{ m}$ .

Describe the nature and range of the two main forces acting between these two protons.

Here is some data for a nucleus of phosphorus-32 ( $1532P^{32}_{15}\text{P}$ ) and a nucleus of uranium-238 ( $92238U^{238}_{92}\text{U}$ ).

Use the data to:

describe the composition of the nuclei before and after the decay in terms of hadrons and quarks
show that both nuclei have approximately the same density.
