SUMMARY
The discussion focuses on calculating the electric field vector E(x,0,0) due to two point charges (Q>0) located at coordinates (0,a,0) and (0,-a,0). The formula used is E = 1/(4πε₀) * Q/r², where r² = x² + a². Participants emphasized the importance of resolving the electric field components along the x and y axes to find the resultant vector. Clarification was provided on handling the direction of the electric field vectors, which have the same magnitude but opposite directions along the y-axis.
