To find the electric field on the axis of a charged disc, we can follow these steps: ### Step 1: Define the Problem We have a charged disc with uniform surface charge density \( \sigma \) and radius \( R \). We want to find the electric field at a point \( P \) located at a distance \( x \) from the center of the disc along its axis. ### Step 2: Consider an Elemental Ring To find the electric field, we consider an elemental ring of radius \( r \) and thickness \( dr \) on the disc. The area of this ring is given by: \[ ...
