SUMMARY
The discussion centers on determining the charge density ρ(r) that generates the electrostatic field E = g|r|r, where g is a constant. The user initially attempted to apply Gauss's law using the divergence of E, expressed as div E = ρ/ε0. However, they encountered difficulties in calculating the divergence in Cartesian coordinates. A suggestion was made to utilize spherical coordinates for a more straightforward calculation, referencing the Wikipedia page on divergence for guidance.
