+ | There are a few approximations and assumptions we should make in order to simplify our model. | ||
* There are no other charges that contribute appreciably to the flux calculation. | * There are no other charges that contribute appreciably to the flux calculation. | ||
* The cylinder is aligned with respect to the line so that its bases are perpendicular to the line, and its wall is parallel (as described). This is just a geometric simplification for the model, and ensures the electric field through the cylinder wall is constant as the wall will be at a uniform distance away from the line of charge at any point. | * The cylinder is aligned with respect to the line so that its bases are perpendicular to the line, and its wall is parallel (as described).
