JEE MainPhysicsElectrostaticsMCQ+4 / −1
A line charge of length a2\frac{\mathrm{a}}{2}2a​ is kept at the center of an edge BCB CBC of a cube ABCDEFGH having edge length 'aaa' as shown in the figure. If the density of line charge is λC\lambda \mathrm{C}λC per unit length, then the total electric flux through all the faces of the cube will be ‾\underline{\hspace{2cm}}​ . (Take, ϵ0\epsilon_0ϵ0​ as the free space permittivity) JEE Main 2025 (Online) 22nd January Morning Shift Physics - Electrostatics Question 33 English
