Hi guys, now in this column we are given to us two dipoles.
00:03
This is p1 and this is what p2.
00:06
These are the two dipoles that we have.
00:09
Sorry, this is like this.
00:14
Okay, this is p1 and this is p2.
00:19
Distances between them is what given to us are.
00:25
We need to find your torque due to p1 on p2.
00:31
Torque due to p2 on p1.
00:33
This is r.
00:35
For p2 dipole, p1 is what axial position.
00:40
So i would say that the electric field due to p1, electric field due to p2, sorry, the e2 is equal to, since it is an xl position, so this is 2k, divide by rq.
00:55
And we know that torque is equal to, what torque is equal to? this is p2.
01:01
Torque is equal to, this is torque due to p2 on p1.
01:07
So this is p12, this is p cross of e...
