SUMMARY
Charge density in coaxial cables is calculated using the relationship between electric field and capacitance. The line integral of voltage is essential for determining the electric field, which is then used to find charge density. The dielectric material must be considered, as it influences the capacitance per unit length between the inner and outer conductors. The solution involves integrating the electric field to derive the charge density accurately.
