摘要
以真空中的两个点电荷为研究对象,讨论了空间坐标系下电势为零的点所形成的轨迹,以及电势为零的点的场强大小及方向;并通过MATLAB进行数值模拟,验证了结论的正确.总结了空间场强求解的一般方法和要点,明确了场强的空间分布性.
For a system with two point charges,the trajectory when the electric potential equal to zero is deduced in the whole space.Also,we discuss the values and directions of field strength under rectangular coordinate systems in the spots of zero electric potential.Numerical simulation with MATLAB is presented to verify the theoretical conclusion.The general approach for solving the problem of electric potential and field strength is summarized.
