对一道关于“双带电圆环轴线上电场强度和电势的分布情况”的物理试题进行定量计算,得到电场强度和电势的分布情况与双环的距离有关,进而对双环距离取不同值时进行讨论,运用计算软件绘制出不同条件下电场强度和电势的分布图像,猜想并尝试证明临界距离的大小. The quantitative calculation of a physical test on the distribution of electric field intensity and potential on the axis of a double charged circular ring shows that the distribution of electric field strength and electric potential is related to the distance of the bicyclic ring and thus takes a different value for the double ring distance Discuss, use computing software to draw the distribution of electric field intensity and potential under different conditions, guess and try to prove the size of the critical distance.
