SUMMARY
The discussion focuses on calculating the electric field at the third corner of a triangle formed by two point charges, specifically q1 = -11.3 μC and q2 = 15.4 μC. The correct magnitude of the electric field is determined to be 1.07e+07 N/C at an angle of 71.2 degrees above the -x-axis. Participants emphasized the importance of unit conversion and the impact of charge signs on the direction of the electric field. Miscalculations were attributed to incorrect unit conversions, particularly between microcoulombs and centimeters.
