Through qualitative analysis and quantitative measurement, we conclude from the force analysis of moving charges that the acting force between the two moving charges of the same kind in the same direction and velocity is mutually exclusive.

• 采用定性分析和定量计量的方法,通过对运动电荷的受力分析,得出两个同向、同速运动的同种电荷间的作用力是相互排斥的结论
