1. Images of the construction of multifocal curves corresponding to the potential lines of the electrostatic field
Shown here are images of the "equipotential" lines for various "charge" configurations, which were obtained using the applet.
Equipotential lines for the configuration q1=+1, q2=+1
Equipotential lines for the configuration q1=+1, q2=-1
Equipotential lines for the configuration q1=+1, q2=-5
Equipotential lines for the configuration q1=+1, q2=1, q3=-0.8
Equipotential lines for the configuration q1=+1, q2=1, q3=-0.8, q4=-0.7
Equipotential lines for the configuration 9 charges
