A brief comment on the numerical results in ‘Electrostatic potential of a uniformly charged triangle in barycentric coordinates’

In a recent paper (2021 Eur. J. Phys. 42 045205), Kim etal carry out an analytical effort to arrive at an expression for the electrostatic potential due to a uniformly charged triangle. This appears to have been attempted by other authors before, with similar, but not exactly equal, numerical results. In addition, the paper leaves some doubts with regard to the comparison of the analytical expressions by different authors and the agreement of their numerical results. What, then, is the true electrostatic potential of a uniformly charged triangle? This comment does not answer this question but provides an independent effort to confirm the numerical results.

对“重心坐标中均匀带电三角形的静电势”的数值结果的简要评论

在最近的一篇论文 (2021 Eur. J. Phys. 42 045205) 中,Kim等人进行了一项分析工作,以得出由均匀带电三角形引起的静电势的表达式。这似乎已经被其他作者尝试过,具有相似但不完全相同的数值结果。此外,本文对不同作者的解析表达式的比较及其数值结果的一致性存在一些疑问。那么,均匀带电三角形的真实静电势是多少?该评论不回答这个问题,但提供了一个独立的努力来确认数值结果。
