The discussion centers on finding resources for calculating electric fields through integration for an evenly distributed disk and a hollow ring, specifically focusing on the on-axis solution. Users share links to various educational websites that provide some guidance on the topic but acknowledge that many skip crucial steps in the mathematical process. One participant offers a unique derivation approach for a disk of finite thickness, suggesting that this might clarify common confusions about the idealization of an infinitely thin disk. The conversation emphasizes the need for detailed explanations and encourages users to specify which parts of existing resources lack clarity. Overall, the thread highlights the challenge of finding comprehensive educational materials for this specific physics problem.
