SUMMARY
The discussion centers on the discrepancy between the teacher's solution, which uses 2π, and the textbook's equation, which employs 4π, in calculating the electric field due to a point charge. The confusion arises from the context of the problem, specifically the presence of an infinite line of charge along the z-axis. The correct application of these constants is crucial for accurate calculations in electrostatics.
