Question

A line charge of length 2 ’ a ’ ​ is kept at the center of an edge BC of a cube A BC D EFG H having edge length ' a ' as shown in the figure. If the density of line charge is λ C per unit length, then the total electric flux through all the faces of the cube will be _______. (Take, ϵ 0 ​ as the free space permittivity)

​ Charge of the line charge = 2 aλ ​ Portion of wire inside cube = 4 1 ​ ∴ q e n ​ = 4 1 ​ ( 2 aλ ​ ) = 8 aλ ​ ϕ = ε 0 ​ q e n ​ ​ = 8 ε 0 ​ aλ ​ ​
