So in this question, here is a situation.
00:05
We have a cylinder, all right, which is definitely uniformly charged.
00:14
Sigma is the surface charge density.
00:17
Radius is also given capital r.
00:22
And then we have another charge wire.
00:27
There is a charged wire.
00:29
All right, which is passing through the axis.
00:32
Another charged wire.
00:34
Lambda is given as linear charge density.
00:37
We need to find the electric field in region one and region two.
00:43
Region 1 is inside and region 2 is outside.
00:47
So let us do this.
00:49
This is very simple.
00:51
Take a gaussian surface here.
00:55
Take this gaussian surface.
00:56
No flux will pass through this surface.
01:00
No flux will pass through this surface...
