摘要
本文系统地计算了一均匀带电球面当其球心在正方体对角线上任意位置时,带电球面对正方体一个面的电通量.结果表明,该面的电通量与带电球面的半径和其所处位置密切相关.当带电球面半径较大时,电通量呈现明显的双峰结构,但是随着半径变小,双峰逐渐接近,最后变成点电荷的结果.
In this paper, the electric flux on each side of the cube is systematically calculated while a uniform charged sphere surface on the diagonal of a cube. The result shows that the electric flux on each side is closely related to the radius and the position of the charged sphere surface. When the radius is larger, the electric flux exhibits an evident double-peak structure. But with the radius decreasing, the distance between the two peaks shortens, and finally it de-generates into a result of a point charge.
