Okay. And this problem. We have charges organizing the square so you could say charges on the square. The length of square is about eight centimeters. We have a charge of Q on one corner, a charge of of two. Q on another corner, three Q and two. Q. I believe this is in a particular order. We also know the charge is equal to 3.1 micro Coolum. Let's draw out what we're talking about, right? These air in a counter clockwise order. Cue to cue. We have negative three to you and took you. All right. We're asked to find the total electrostatic energy this configuration we can use, using the fact that you is equal to Q V for a particular pair of potentials. And we need to add up all the pairs of potentials so we would have you is equal to one over for pie. Absolutely not. Do you want you to over the distance between the two of us? Q. On Q three. This is between one and three. You want you for just one of four. You see the pattern. Do it for all possible pairs. One more term doing for our 34 Good. And so we just need to be careful about what these distances are for using our. And because she was the same in all cases, we could simply pull it. Q. Score it out for Priceline nuts. So we have. Oh, actually, it is not that simple. Let's let's take a step back. So are two Charges are different in this case of different on every corner, so we have to be much more careful. So this case, we would have ah Q to Q over l. Let's cue negative. Three. Q over route to l gonna count that cross diagonal distance? Let's cue to cue or l was to Q native freak you over. L was to Q uh, three. Q over to L. You see the idea? I get three to do this to exhaustion, to chew over L. Okay, so we got a bunch of terms now. He should do able to simplify this all down. We say we have a Q squared and every single one of these terms. We're gonna pull it out. Let's go to different page. Finish this up. So pulling at you squirt out if you get Q squared over four pipes or not. When it was always said and done, we end up with eight of a route to Oh, and also we can pull a little out there. Oh, this little mistake there, brother, we're talking about one over route to minus aid would be what this is, what it's simplified, which will come out to be after playing in our charge of. Q. What show actually show the steps you have 3.1 to 10 the negative six glum square that for pie. Of the four pipes or not, we can just have calculated at all on its own. Just so we have 0.8 meters for a distance for l. We have about 90%. The nine Newton meters squared Colome squared. That's our one overflow camps are not. And lastly, we pulled by all this by one by one of her two minus a, and we will get for answer negative 7.9 jewels and that's it.
