Question

So here's one I find oddly worded, but there's probably someone who can read this much better than I can.

So basically the problem is this:
A cylindrical distribution of charge p = a/sqrt(r) where a = 2 µC/m^(5/2) extends from 0 cm to 9.6 cm. Concentric with this is a dielectric shell with 2.21 of inner radius 17.3 cm and outer radius 24.2.

What is the electric field at 4.09 cm? Answer in units of V/m.

My attempt:
p = a/sqrt(r)
E = ?

a = 2 µC/m^(5/2)
r1 = 17.3 cm
r2 = 24.2 cm

I know that I'm looking for the value of the electric field, but I have no idea how to apply this to get the answer.

Explanation / Answer

Ok rate this as lifesaver first. I am sick and tired of people taking advantage of me. I spend 30 minutes to one hour posting a solution and then they just take the answer and dont rate it. Inbox me once you have rated it and I will send you the solution.
