摘要: 指出<大学物理>1999年第9期上的一篇文章在用虚功原理求二静电体系间互作用力时的欠妥之处,并简要分析了其原因,给出了正确的算式.

关键词: 虚功原理, 互能, 自能, 总能

Abstract: In an article elsewhere, the formula is not suitable when finding the solution of mutual acting force between two electrostatic systems in the virtual work calculation, thus, the conclusion is not correct. The reason is analysed and the error is corrected.

Key words: principle of virtual work, mutual energy, self-energy, total energy
