Question 31 – Nuclear and particle physics - Questions

Two protons in a highly compressed stellar core are separated by a distance of about $0.40 \times 10^{-15} \text{ m}$ .

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

Here is some data for a nucleus of carbon-11 ( $611C^{11}_{6}\text{C}$ ) 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.

Take $kg1\text{ u} = 1.66 \times 10^{-27}\text{ kg}$ .
