electric flux i suppose //

tanθ = R/L

charge through one slice of disc = dq= 3Q/L3 x2dx

since it is an uniformly charged solid cone,
the field due to the charge will be symmetrical about the central line .

and, the horizontal feilds will cancel each other, leaving only the vertical
component.

so lets take a disk and find its flux.

dφ = q/ ε0 = 3Q/L3ε0 x2dx

=> φ = ∫ 3Q/L3ε0 x2dx (from x=0 to L)

=> φ = Q/ε0.

(this is the most weird result i had expected.)
