Lines of Force for Two Point Charges

Resumen
Basics of static electricity In this demonstration two-dimensional equipotential contours fi(x,y), representing cross sections of equipotential surfaces, were plotted for two point charges of variable magnitude and location. It was also possible to make a vector plot of the corresponding electric field E(x,y). It is much trickier to plot the lines of force emanating from a positive point charge and converging on a negative point charge. These are everywhere tangent to the electric field vectors and form a set of contours psi(x,y), shown as red curves, everywhere orthogonal to the equipotentials fi(x,y), shown in gray Componente Curricular::Ensino Médio::Física Componente Curricular::Educação Superior::Ciências Exatas e da Terra::Física
