本文中复合场包括下列三种情况:(1)某一区域重力场、匀强电场、匀强磁场并存,简称三场并存;(2)某一区域匀强电场、匀强磁场并存,简称电、磁场并存;(3)匀强电场与匀强磁场分区域存在,简称电、磁场分存.带电粒子(体)在复合场中运动的问题是高考的重点与难点,试题以计算题为主,由于带电粒子受力与运动的复杂性,这类题目对学生综合应用物理知识解决问题的能力以及应用数学知识解决物理问题的能力要求较高.本文通过典型的例题分析,总结相应的解题思路,指出解题中容易出现的问题.希望对学生学习本专题有所帮助.一、带电粒子(体)在三场并存区域中的
The composite field in this paper includes the following three cases: (1) Gravitational field, uniform electric field and uniform magnetic field coexist in a certain area, simply referred to as coexistence of three fields; (2) Uniform strong magnetic field coexists in a certain area, , The coexistence of magnetic field; (3) uniform electric field and uniform magnetic field exist, referred to as electricity, magnetic field. Charged particles (body) movement in the complex field is the focus of college entrance examination and the difficulty of the test questions Due to the complexity of force and movement of charged particles, such topics require students to comprehensively apply physical knowledge to solve problems and to apply mathematical knowledge to solve physical problems.This paper summarizes the corresponding problems through the typical example analysis Ideas, pointed out that the problem-solving problems that are easy to appear in the hope of helping students learn the topic of help. First, the charged particles (body) in the three coexisting areas
