Infinite Non-Conducting Slab with Variable Charge Density | Force of Interaction | JEE Advanced

This is the link to the problem, you can practice and see solution: https://physicsma.com/practice?proble... In this video, we break down a medium-difficulty JEE Advanced electrostatics problem focusing on continuous charge systems and the force of interaction. We step through the exact analytical process of calculating the magnitude of the force per unit area applied by one half of an infinite solid non-conducting slab on the other half. This specific slab features a variable volume charge density given by rho(x) = rho_0 * (|x| / l). *Key Concepts Covered in this Solution:* *Applying Gauss's Law:* We construct a cylindrical Gaussian surface to find the enclosed charge and calculate the electric field E_x inside the slab for x between 0 and l. *Integration for Force:* We consider an infinitesimally thin sheet of the slab to calculate the elemental force dF, then integrate from x = 0 to x = l to find the total force per unit area. *Final Derivation:* Step-by-step simplification to arrive at the correct final magnitude of (rho_0^2 * l^2) / (8 * epsilon_0).
