SUMMARY
The discussion focuses on calculating the electric field generated by a nonconducting wall with a uniform surface charge density of 8.55 µC/cm². The relevant equations used include the surface charge density formula (σ = Q/A) and the electric field equation (E = σ/2ε₀). The correct calculation for the electric field at a distance of 8.55 cm from the wall is E = 8.55 µC/cm² / (2 x 8.854 x 10^-12 F/m), confirming that the distance does not affect the electric field in this scenario, as long as it is small compared to the wall's dimensions.
