在静电学中,库仑定律作为独立的、基础的内容定量揭示了真空中点电荷间相互作用力所遵从的规律,在库仑定律基础上,利用库仑定律与万有引力定律的相似性,我们才能研究电场力的性质与能的性质这两个电场的核心内容,不仅如此,库仑定律还直 In electrostatics, Coulomb’s law quantifies, as an independent, basic content, the laws followed by the interaction forces between point charges in a vacuum. On the basis of Coulomb’s law, by using the similarity between Coulomb’s law and the law of universal gravitation, we can study electric fields. The nature of the nature of the force and the nature of the energy are the core contents of these two electric fields. Not only that, the Coulomb’s law is straight.
