Expert Answer
Electrical field at a distance r from contnuous line charge = λ/(2πr εo)
where λ is charge density per unit length.
Flux over a surface = Normal Electric field intensity × Area
let us consider a circular strip of curved surface of cone as shown in figure, whose radius is r and strip width is d.
Electric field intensity normal to the surface area = 
= E cosθ , where θ is the semi angle of cone.
= E cosθ , where θ is the semi angle of cone.Flux through the surface of circular strip = Ecosθ×(2πr dh) = [ λ/(2πr εo) ] cosθ ×(2πr dh) = ( λ cosθ ) dh / εo
Total flux through the curved surface area of cone =
