Answer -
Charge density of the long charged cylinderof length┬аL┬аand radius┬аr┬аis┬а╬╗.
Another cylinder of same length surroundsthe pervious cylinder. The radius of this cylinder is┬аR.
Let┬аE┬аbe the electricfield produced in the space between the two cylinders.
Electric flux through the Gaussian surface is given byGaussтАЩs theorem as,
Where,┬аd┬а= Distance of apoint from the common axis of the cylinders
Let┬аq┬аbe the total chargeon the cylinder.
It can be written as
Where,
q┬а=Charge on the inner sphere of the outer cylinder
тИИ0┬а= Permittivityof free space
Therefore, the electricfield in the space between the two cylinders is┬а
