电场的主要问题是电场性质的描述和电场对电荷的作用,解题时必须搞清描述电场性质的几个物理量和研究电场的各个规律。考试中难点是带电粒子在(复合)场中的运动。笔者认为主要存
The main problem of the electric field is the description of the nature of the electric field and the effect of the electric field on the charge. When solving the problem, we must find out several physical quantities describing the nature of the electric field and study the laws of the electric field. The difficulty in exams is the movement of charged particles in the (composite) field. I think the main deposit
