We calculate the electrostatic potential and electric field of a uniformly charged disk everywhere in space. This electrostatic problem was solved long ago, and its gravitational analogue - even earlier. However, it seems that physics students are not aware of the solution, because it is not presented in textbooks. The purpose of the present article is to fill this gap in the pedagogical literature.

关于均匀带电圆盘的静电势和电场

我们计算了空间各处均匀带电圆盘的静电势和电场。这个静电问题很久以前就已经解决了，它的引力类似物——甚至更早。然而，物理专业的学生似乎并不知道解决方案，因为它没有出现在教科书中。本文的目的是填补教学文献中的这一空白。
