本文利用绘图软件绘制出不等量异种电荷的等势面,通过点电荷电势公式推导出不等量异种电荷的零等势面为球面.
In this paper, we draw the equipotential surface of unequal quantity of different charges by using the drawing software. We derive the zero equipotential surface of the heterogeneous charge by the dot charge potential formula as the spherical surface.
