Question

Calculate the magnitude of the electric field at any point between the cylinders a distance rr from the axis. Express your answer in terms of some or all of the variables aaa, bbb, ccc, rrr, λλlambda and constants ππpi and ϵ0ϵ0epsilon_0.

Answer 1

Answer:

Explanation:

we have two concentric cylinders, by using the Gauss' law we have

$E(2\pi r L)=\frac{Q}{\epsilon_{0}}=\frac{\lambda L}{\epsilon_{0}}\\E=\frac{\lambda}{2 \pi r \epsilon_{0}}$

where λ is the cahrge per unit of length in both cylinders, r is a point between the cylinders

I hope this is useful
