从“处于静电平衡的导体 ,内部场强处处为零 ,导体是等势体”等性质出发 ,并利用电场线这一形象工具 ,可以定性地讨论导体静电平衡的一些问题 ,但是 ,在高中物理教学中 ,对于导体表面上感应电荷的分布问题 ,常常会由于“想当然”而出现错误 .针对这种情况 ,笔者最近在给高中物? From the nature of the “Electrostatically balanced conductor, where the internal field strength is zero, the conductor is the isopotential” and other properties, and using the image tool of the electric field line, some problems of the electrostatic balance of the conductor can be qualitatively discussed, but in the high school physics In teaching, for the distribution of the induced charge on the surface of the conductor, errors often occur due to “takes it for granted.” In response to this situation, the author has recently given high school subjects?
