在电场这一章节的学习中,由于它具有知识面广、联系物理知识的范围大等特点,学生在解题中,有很多典型的错误,如果教师在教学过程中,及时指导将起到事半功倍的作用.笔者把它整理出来,作为高中教学(尤其是复习)之用.典型错误之一、套用圆周运动的条件而出错例1 如图1所示,一半径为 R 的绝缘圆形轨道竖直放置,圆轨道最低点与一条水平轨道相连,轨道都是光滑的,轨道所在空间存在水平向右的匀强电 In the study of electric field this chapter, due to its wide range of knowledge, the scope of the contact physical knowledge and so on, the students in the problem-solving, there are many typical mistakes, if the teacher in the teaching process, timely guidance will play More effective. I put it out, as a high school teaching (especially review). One of the typical mistakes, the conditions apply circular motion error Example 1 As shown in Figure 1, a radius of the R circular orbital Vertical placement, the lowest point of a circular orbit connected to a horizontal track, the track is smooth, the track where the space there is horizontal uniform power to the right
