00:01 Hi there, so for this problem we have the situation that is shown in here.

00:04 We have three charges that form a triangle as is shown in here.

00:08 The sides of all of these triangles are the same, one centimeter.

00:11 So the question for this is to determine the magnitude of the force f on the one nanocolon's charge.

00:19 So we know, let's just draw the forces, okay? let's just label this charge as q1 and this other charge as q2.

00:30 And then this charge as q3, okay? so we want the force, the resulting force, on the charge of one nanocolumns, on the charge q3.

00:40 So then, depending on whether the charge, the charges have the same sign, the force is going to be repulsive, or if one is negative and the other is positive, then the force is going to be attractive.

00:59 In this case, because of q1, the force is going to be repulsive, okay? so let me just draw that situation in here.

01:09 We go from here.

01:11 So for example, this force, let's label this as the force 1, 3.

01:17 And the other one is going to be attractive because they have opposite, because they have different signs, okay? so then we will have something like this.

01:28 Along this direction so yes that's what we have in here and then this way is what we are going to label the force two three so as you can see what if we add their um x components their um horizontal components we will cancel that and then the magnitude that we will obtain well let let me just draw that.

02:06 If we do this with a sum of vectors, we will have that the resultant vector should be only in the x component...
