WebAnswer (1 of 2): The electric field of a line of charge can be found by superposing the point charge fields of infinitesimal charge elements. UY1: Electric Potential Of An Infinite Line Charge. You don't have to assume there is no axial component - it will become apparent when you do the derivation. To solve surface charge problems, we break the surface into symmetrical differential stripes that match the shape of the surface; here, well use rings, as shown in the figure. What is this fallacy: Perfection is impossible, therefore imperfection should be overlooked.
