SUMMARY
Gauss's Law is not applicable for calculating the electric flux density of a charged disk due to the lack of symmetry, which prevents the construction of a suitable Gaussian surface. In contrast, Coulomb's Law can calculate the electric field at any point, but deriving a general formula for electric flux density near the disk requires complex calculations, often resulting in an infinite series. Advanced techniques such as Green's function are necessary for solving Poisson's equation in graduate-level electromagnetism courses, particularly when using texts like Jackson.
