Now here in this question, we have two point charges.
00:03
The first charge is located at x equals 2, y equals minus 2.
00:08
So let me first draw a coordinate system, which is something like this, x, y.
00:22
Then the first charge is located something where x 2 meters, y minus 2 meters.
00:28
So it will be something like where somewhere here.
00:31
So that's first charge, which is located at 2.
00:34
2 minus 2.
00:35
That's position of it.
00:37
So the charge has a value, which is i would call a q1, which is actually minus 3 macron colon.
00:47
And there's another charge which is located at x equals 1, y equals 4.
00:51
X equals 1, y, 4 somewhere here.
00:54
So it's 1.
00:56
And this judge has a value, which is 12 macron column.
01:03
And you're asking about the electric field generated by these two charges at the point.
01:11
Well, for which x equals minus 1, y called 0 ,0, it basically looks at a pointer here, right? that's the point of p we have been to look at.
01:20
What's the electrophied at this point? well, the electrified, of course, has the electric at this point, of course, is the sum of the electric field generated by the charge q1 and q2 at this point, right? so the charge, the electric generator generated by this charge q2, q2 is a positive.
01:38
So the charge is going to, in this direction, right? that's the, i would call it e2.
01:44
That's the electric filter generated by charge 2.
01:47
And another electric field, the electric field by charge q1 is going to be like this, is going to go toward this q2, this q1, right? like this, so it's going to be at this.
02:02
That is another, that's e1, okay? and the total electric field, of course, it's given by e1 plus e2, right...
