两个带电物体作用力的讨论

Discussion of interaction force for two objects with charge

以点电荷库仑定律为基础 ,用分离变量法和镜像法讨论带电导体球的电荷分布 ,得到带电导体球与点电荷之间的相互作用力公式 ,对公式进行讨论得到带同 (异 )种电荷的物体在什么条件下表现为斥 (引 )力 ,什么条件下没有作用力 ,什么条件下为引 (斥 )力 .

Basing on the Coulomb′s Law and using the method of separating-variable and the method of mirror-image to analyze the charge distribution for spherical conductor with charge, the interaction force formulas about the spherical conductor and the dot-charge are derived, and the formulas are discussed.
