For practical case we will analyze this given can figuration in cylindrical co-ordinate system r,∅,z

Charge for $\dfrac{dL}{dz}$ section is given as

$dQ=ρ_L .d_L=ρ_L.d_z$

As $d_z- 0$ , we can apply point charge concept for $d_z$ section.

$d \bar{E}=\dfrac{dQ}{4πεR^2} \overline{a_R} \\ d \bar{E}=\dfrac{ρ_L.d_z}{4πεR^2} \overline{a_R} \\ \bar{E}= ∫_{z= -∞}^∞ \dfrac{ρ_L.d_z}{4πεR^2} \overline{a_R}………(1) …
