等量同种电荷中垂线上的场强最值位置探讨及迁移

本文主要介绍等量同种电荷中垂线场强的最大值的基础上,具体确定最值的位置。介绍对场强表达式最值的三种求解方法,从定性到定量。此模型,还可迁移到均匀带电圆环中轴线场强的分析上,帮助学生拓展思维。

in this paper,we mainly introduce the maximum value of vertical field intensity in the same charge,and specify the position of the maximum value.This paper introduces three methods of solving the maximum value of field strength expression,from qualitative to quantitative.This model can also be transferred to the analysis of the field strength of the central axis of the uniformly charged ring,to help students expand their thinking.
