【摘要】 实际中,一般情况下,一定电荷分布的电荷体系在外电场中的位置发生变化时,外电场的分布情况和产生外电场的电荷分布情况会随之而发生变化。本文分析了这种情况下电荷体系在外电场中的能量(势能),并根据势能分析研究了电荷体系的受力情况。更多还原

【Abstract】 in fact,under normal circumstances,when A certain charge distribution of the position of charge system has changed in the outside electric field,the distribution of electric field and product the charge distribution of electric field Will change subsequently,in this case the paper analyzes the energy( potential energy)of Charge system which is in an electric field,And according to the analysis of the potential energy it studies the force situation of charge system.更多还原
