In the figure the four particles form a square of edge length a = 5.00 cm and have charges q1 = +10.0 nC, q2 = -20.0 nC, q3 = 20.0 nC, and q4 = -10.0 nC. What is the magnitude of the net electric field produced by the particles at the square's center?

I was wondering why dosen't all of the y-components cancel as well?

how come for the y component, the charges do not cancel out as well?

Why do we assume there is a positive charge in the center? That's the only part I don't understand.

thank you!! i do understand the concept but when i do the calculation, i didn't get the same answer as you did. why didn't you find the distance first? i did that and i found out that the answer isn't the same because of that

why doesn't the y -value cancel out?
