摘要
本文从库仑定律出发,利用场强迭加原理,计算了均匀带电园环上两个特殊部分对电场的贡献,在极限条件下,找到了园环附近的电场分布与无穷长均匀带电直线的场相似的原因,并指出了二者相似的物理机制。
In this paper. we make use of Coulonb's law and composition low of electric field, calculate the compound electric field about two particular parts of an uniformly charged circle. In the limit condition, we find cause that, two electric fields are similar produeeing in the uniformly charged circle nearby and in the infinitely long straight uniformly charged line, then point out their physical mechanism.
