Answer :
Answer:
Explanation:
we have two concentric cylinders, by using the Gauss' law we have
[tex]E(2\pi r L)=\frac{Q}{\epsilon_{0}}=\frac{\lambda L}{\epsilon_{0}}\\E=\frac{\lambda}{2 \pi r \epsilon_{0}}[/tex]
where λ is the cahrge per unit of length in both cylinders, r is a point between the cylinders
I hope this is useful
