So So currently we're beginning again. Therefore we're going to look in ~ the instance where we have actually to suggest charges and we're going to take it a look at the electric field the calculated because that them along the way. And so I've currently started right here by drawing our situation. Therefore we have our 2 charges, uh, minus six suggest two five and a clue here and also then minus twelve suggest five mental, two rooms below on the right, and we're walk to take a watch att both suggest a and point feet and also calculate the electrical field there. And then also from port on electric, felicity and also so because that party. And we desire to calculate the election ar that point a here, created by these two point charges. For this reason thankfully, we obtained them in the line and also we're just going to take it a look at the equations us need. Therefore on electric field from suggest charge one over four pi. I'm no time cute. Simply the fee of the fast turn over r squared the distance to the point. And also then we likewise want to store in mind the e total. At part point, it's just going to equal through some of all of the electric fields from every one of the point charges acting on it. Okay, therefore in arcades the this is walking to be even. Space you eating plan? We need to to safeguard it. And also then you desire to store the mind. Likewise value because that one over four pi ups or not, you room conversant same to nine. Ten come the ninth. Noon time meter squared. Coolum squared. Okay, so now it's actually then calculate this green. So also so, we'LL contact of the charge in the center Here, charge one equal to one over four pi. It's not time to end our square. So space in this case, is walk to it is in fifteen centimeters. Thank you. Uncover a six point two 5 nano Cool. Um yet we want the value, no my unit. Therefore we're gonna have to move Nano Cruella Mine is mine alone and also then we want to perform meters, centimeters, centimeters No should be relatively comfortable law that. And now eat too. So right here thinks we'LL get a little bit tricky. So here we have actually actually the fee on opposing side. And also so few of the negative charge more than I have to flip that sign due to the fact that it's walking to provide thie officer contribution. Oven must feel here for this one. We're just going to call positive and also the street ten top top emissions squared. And also so as soon as you take the time to plug in the number here and also actually they calculate it, that will contact it Okay, it's walking to it is in equal. One, three, seven i zero never ever her cool pet. So fairly easy enough. The only suggest we need the psychic is method have this good convention. Therefore it's pretty easy to see from the photo itself. We have to same discover charges, but they're on the contrary five, and we want to watch at every they're going come ask girlfriend there. And also if you're familiar with the beat of physics, it's type of favor a destruction destructive interference. Okay, possibly that's for later date. For this reason we'LL move on to a party where we're going to record anything, what to feeling at point B end here, and so we're walking to carry out the precise same way. So you won is walk to be this male here and so us don't have to do anything with the charges. We have the right to just carry this negative. Fine. All the way through. And then we have actually Q to find a six suggest two five, girlfriend know? Nah, no. Cool. And also then now our street again. Ten centimeters clear. Okay, therefore you might remember the ten to the minus nine here. Me too. Covenant. Defector. Have one over because that pie on that time. Twenty five, then a cruel, um, again, he remembers that Nano Coolum below in right here will, uh, publication each various other out, man than several of all the street here. So it's walking to be thirty 5 centimetres. Suggest three 5 leaders and squared. Okay, relatively easy sufficient to perform in this case. So, uh, only calculation come you, however you should be quite comfortable sufficient here when we go out to few of the two electrical field. And also we addressed up turn off the electrical field, pointy and the electrical energy of the point. Give thanks to you. No, finally part. See, we want to try and uncover the force If us played a proton now and allude day, so, yeah, we're blue protest since remember that a proton has actually the hard of girlfriend one suggest times ten come the minus nineteen. Cool. Okay. And also so now, here We're walking to require an equation for fourth Colonel Electric and also some charges. So electrical force going to it is in Q time. Therefore you being the charge that we're handling the charge will certainly be the fee of the proton and easy. So now that we're handle with suggest A, this is walk to be he's electrical field the fourth, eh? This same to cue the proton. So this guy shows up this item time? Yeah. Whereby is the electrical field the calculated end here. Therefore that's one three seven 5 zero Newton curriculum. So hee okay. And also again, we'LL leaving the calculation to you. However at this point, you need to be fairly comfortable with the case we're dealing here, so there's nothing come tricky right here we have. Ah, the fourth. And also so we deserve to remember once we desire Teo in reality take the direction here. And so the direction of this pressure is walk to it is in going this ar right waken watch this fairly easily. We have ah, positive. Ah, charge right here being the proton and also then we have actually the larger an adverse charge over here and also it's a shorter distance away. For this reason you're gonna have a stronger pressure going in this direction. And also so we might say the direction below should it is in too right gently. Okay. And also there is her problem. You're finished. No, man. What carry out I do? What else? What else execute I do? my film.
