关于库仑平方反比定律的证明

On the Certification of the Coulomb Law of Inverse Ratio to the Square

库仑平方反比定律是电磁学的基本定律之一.它是通过卡文迪许实验得到验证的.在论述验证理论时,通常用的是间接证法,而本文对此问题用数学方法进行直接论证,并导出了数学公式.这样在逻辑上更为严谨,有利于提高学生的分析能力.

The Coulomb law of inverse ratio to the square is one of the basic laws of electromagnetics. It is verified through Cavendish experiment. Expounding the thoery of verification, the indirect method is generally used. But in this paper, a mathematical method is used to directly expound this problem. And the formulas about it have been obtained. That is more rigorous in logic, and is favorable to improve the students' analysis abilities.
