带电粒子在电场中的加速和偏转是电场中最重要的应用问题.当带电粒子所受电场力与速度方向在同一直线上时,粒子将做加速或减速直线运动,此类问题重在考查学生灵活运用动力学规律解决动力学问题的能力,因此在考题中屡见不鲜.本文着重讨
The acceleration and deflection of charged particles in the electric field is the most important application problem in the electric field. When the electric field force and the direction of the velocity of the charged particles are on the same line, the particles will accelerate or decelerate the linear motion. Such problems focus on examining students. The ability to flexibly use dynamic laws to solve dynamic problems is common in exam questions. This article focuses on
