在计算匀强电场中几何图形中的电势问题时,应用以下规律求解有关问题时相当简洁、快捷.现介绍如下:规律1匀强电场中同一直线上任意线段两端点间的电势差与这两点间的距离成正比.在如图1所示的匀强电场中,某直线上的两线段图1MN和PQ,它们两端点间的电势差与其距离的关系为UMNUPQ
When calculating the potential problem in geometrical patterns in a uniform electric field, applying the following rules to solve the problems is quite simple and fast. Now it is introduced as follows: Law 1 The potential difference between two ends of an arbitrary line segment on the same line in the homogeneous electric field and these two points The distance between the two is proportional. In the homogeneous electric field shown in Figure 1, the two line segments on a certain line Figure 1MN and PQ, the relationship between the potential difference between the two ends and the distance between them is UMNUPQ
