All right, so let's say we have a charge, q1, and then two other charges, q2 and q3.
00:07
And we could draw slightly more symmetrically.
00:11
But these charges are separated by a distance of, let's see.
00:18
All right, so 0 .5 meters, which is what this distance is supposed to be.
00:23
So we'll call it d really quickly.
00:26
And we're told q1 is 6, microculems, q2.
00:31
2 is 8 .5 microculems and q3 is negative 6 .5.
00:37
And we're going to find the electric field at this point.
00:40
We'll call it p.
00:41
So let's look at the field in the extraction.
00:44
Luckily, the field in the extraction only comes from q2 and q3...
