SUMMARY
The discussion focuses on the calculation of the electric field generated by two charges positioned on the x-axis, utilizing the equation |E| = (Kq)/r^2. Participants emphasize the importance of considering both the magnitude and direction of the electric field in different scenarios. A suggestion is made to sketch the electric fields near the charges to visualize the differences between the two cases presented in the homework. The conversation highlights the necessity of understanding vector components in electric field calculations.

Hello NPM, 
well, from your relevant equation I wouldn't be able to see a difference! You need something more, about the direction perhaps !
Can you sketch the fields close to the charges in the two cases (there the 'other charge' hasn't got much influence) ?
