Forces and field simulation

Run the simulation Charges and Fields that allow you to place $\pm1\,\rm nC$ charges and view the associated $\vec{E}$-field.

With this simulation you should,

  1. start with one positive charge and view the $\vec{E}$-field,
  2. add a second negative charge and view the $\vec{E}$-field froma dipole, change the distance between the charges and see what happens.
  3. add more charges, and see how the $\vec{E}$-fields sum together.
