Abstract:
This paper describes an interactive didactic tool made with the help of the Mathcad program for the study of the electric dipole. We calculate the potential and the electric field in a point placed at a certain distance from a system consisting of two equal and opposite point electric charges. The electric dipole moment is specified in the input data by the distance between the negative charge and the positive charge and the absolute common value of the two electric charges. By modifying the input data we can verify the calculation relations for the potential and the electric field at a large distance from the center of the electric dipole. The use of this tool in the classroom helps students to more easily understand how the principle of overlapping electric fields is applied in a concrete case and to clarify the connection between the electric field and the electric potential. Similarly, with the Mathcad program, students have the opportunity to efficiently explore the polar coordinates in solving an electrostatic problem and to easily operate with the units of measurement of physical quantities involved in calculations.
