| Abstract: | 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. |
