Okay, So if we look at the diagram that's in the textbook, I modified it a little bit by color coding the charges or the same charges as we see here that the red dots are scene, the green dots are same, and similarly, the blue dots are seen, so the red dots are plus three e. The blue notes are classy, the green dots are negative. Five. And finally, there's a black doctor. Just queue, for that's negative Too weak. Now we see that diametrically opposite charges actually cancel each other because that electric field for the diametrical opposite charges cancel each other. Because we see that cute, for example, que tu and Q six, they have the same charge. So electric Field, produced by Q To will be cancelled by Q six and same thing for these red dots and green dogs. The only charge that will survive here is Q for and Q eight because they are not similar and the direction will be pointing on the right side because Q for his negative and Q eight is positive. Also, to calculate the electric field, we have to add the electric field for Q eight. The magnitude plus the magnitude off electric field for Charles Queue for So for the magnitude, we don't care about the signs. So for Q For this will be, um, twice e divided by four pi Absolute Nordisk red. And for they spark, we'll have e divided by four by absolutely not the spread as well. And then we add them together, which finally will give us treat you over four pipes. Eleanor D squared on that's equal to three e by four pipes learned discord. And then finally, we use the numbers. We see that the electric field is 1.8 times into the bar. Negative five. New convert. So if you're wondering how we got described here, so the way we calculate electric field is we put a unit charge in the middle off cue for and Kuwait and receive that the distance from Q eight and the black small dot here is D. Since and since it's a positive charge, so the electric field will point to the right, and then we have ah, this big black dog queue for and this small dot dot since Q for his negative, So the electric field will be again pointing on the right side and that that's why we get this over. All rights, a direction. So we're calculating the electric field on this point. And because of that, we have this de Aza distance here. And as we mentioned that we're calculating we're taking the absolute value for the electric and so we don't care about the sign of the charges. So that's why we are able to add these two charges. And that's where we got Treat you and three e finally in calculation off net electric field. All right, Thanks for watching. I'll see you next time.
