Question

4. Consider an infinitely long, thin, uniformly charged wire length. Symmetry dictates that the electric field in cylindrical coordinates will have only an r component (i.e. no θ or k components). Use the superposition principle to show that the electric field in cylindrical coordinates is with charge density λ per unit (4.63) 2 Hint: You will find the integral useful 2 )3/2 5. Find an expression for the voltage field around the wire in question 4.

I have used line charge density as
PL

And perpendicular distance between line charge and point P as $\rho$

Everything is mentioned in diagram..
