“同性电荷相斥,异性电荷相吸”一直是我们在讲解电荷间相互作用时的一个结论性总结,它有没有使用的局限性呢?本文根据中学阶段一道常见的带电导体球间的相互作用为例,通过电荷等效分析了不同的材质球间的相互作用问题,发现该结论实际是有使用条件的,从而进一步体现出物理规律的使用范围和使用条件的严谨性,不能随意地等效和扩展类推.
“Same-sex charge repulsion, opposite-sex charge phase absorption ” has been a conclusive summary of the interaction between charges, it has no limitations? In this paper, according to a middle school charged conductor common between the ball For example, by the charge equivalent analysis of the interaction between different material ball problem, found that the conclusion is actually the use of conditions, so as to further reflect the use of physical laws and conditions of use of rigor, can not be arbitrarily Equivalence and extension Analogy.
