00:01
Here, two concentric conductors are there.
00:05
So, let's say this is one conductor and this is another conductor.
00:16
So, here, here is plus q charge, here is minus q charge.
00:24
So, this is the centre let's say.
00:27
And this one is given as r1 and this one is r2.
00:34
Let's say this is the point p at the distance r.
00:43
So, electric field, field between the two conductors at any point, let's say here, any point p at the distance r from the centre equal to what we can say, electric field p into from gauss law, what we can say, it is 4 pi r square equal to the charge, charge enclosed by what we can say, epsilon naught...
