对称性问题普遍存在于高中物理问题中.本文以静电场中的电场强度为例,运用了3种常用的对称性问题求解方法,希望能使师生感受物理教学中的对称美.
The problem of symmetry is common in high school physics.In this paper, we take the electric field strength in the electrostatic field as an example and apply three commonly used methods to solve the problem of symmetry, hoping to make teachers and students feel the beauty of symmetry in physics teaching.
