SUMMARY
The discussion focuses on calculating the electric field intensity and total charge on a gold plate with a surface charge density of 5x10^-9 C/m² and a radius of 15 cm. The electric field intensity (E) near the plate center is calculated using the formula E = ρ / ε₀, resulting in an intensity of 565 V/m. To find the total charge (q) on the plate, the equation q = (surface charge density) x (area of the plate) is applied, confirming that the charge density is constant across the surface.
