摘要: 基于电磁学理论中的镜像法,利用叠加原理和Mathematica 数学软件,计算了均匀带电线状体与接地无限大导体平面和带电导体球的电场力,给出了解析结果,同时绘出了电场力随角度和距离变化的图像.

Abstract: We calculate the Coulomb forces of the uniformly charged linear body and the conductor flat connecting with earth or the electric conductor ball reaction with the mirror image method in the electromagnetic theory.The superposition principle and mathematical software“Mathematica” can be used,thus the Coulomb forces of the image changing with angle and distance are given.
