JEE Main 2025 — Electrostatics Question with Solution
From: JEE Main 2025 (Online) 22nd January Morning Shift
Question
A line charge of length is kept at the center of an edge of a cube ABCDEFGH having edge length ' ' as shown in the figure. If the density of line charge is per unit length, then the total electric flux through all the faces of the cube will be ___________ . (Take, as the free space permittivity)
This question includes a diagram. The text above accompanies the figure.

Step-by-step explanation
, = enclosed charge
here, we need three other identical cubes to enclose the charge fully.
So, total four cubes enclose the charge
