What can you say about two charges $ _{1}$ and $q_{2},$ if the electric field one-fourth of the way from $q_{1}$ to $q_{2}$ is zero?

were given that charges kyu won. And cute too. And there is a point between human and cuter, which is 1/4 off a distance away from Cuban. This 1/4 is often that distance between Q Wouldn't you too? At this point we have We are given that e equals zero. Now if they held up with a sign plus and minus the field, feel will point away from Cuban and towards Que Tu So there is no chance that they there will be a point where it zero similar goes for If this is negative and this is positive So fourth thing that we can say is that Kyu won thank you to have the same charges. Um let me not where it is signed there, Q one Thank you to have same sign. So if anyone is positive, Que tu is positive and que tu is negative than human must be negative as well. No, let's find out one more thing about Cuban and cute. So that is the magnitude relation between them. Now we're given that a distance. 1/4 away from Kyu won, the electric field goes to zero. Now, if this is 1/4 this must be 3/4. At this point, we have e equals zero, so we know that e equals E one minus two. Now I'm assuming that key one is positive. Thank you to is positive as well. So if I assume that this is X axis and this is positive direction, then que Tu has electric field, which is pointed towards negative action. That's why there's a negative sign here. We know that night electric field is zero. The one is K one times Q one divided by our one square minus K Times Q two divided by our two squared. If you simplify this, you will get q one divided by our one square, which is 1/4 squared equals Q two divided by 3/4 where, which is our two square. So you can see from this is that que tu is equal to nine times. Q one
