Excellent I believe I have got the correct answer :D Thank you so much for your help

I am sorry but I don't understand what you mean?

Or should I just use a circular one because the conductor is infinite either side?

A cylindrical surface? With surface area of 2\pirl ?

The integral form of Ampere's law in vacuum is ∫B\cdotdl=μ_{0}I (a) Using the relation between I and J, obtain the differential form of Ampere's law. You may ignore any displacement current. (b)Define the displacement current density J_{d} in terms of the displacement field D and show...

Consider a hollow cylindrical conductor in vacuum with its axis aligned with the z-axis, and with a positive surface charge density σ. The direction of the electric field is radial and its magnitude E is only a function of the distance r from the z-axis, E = E(r). Use Gauss' law to obtain...
