Please show photos using the Phet simulation https://phet.colorado.edu/sims/html/charges-and-fields/latest/charges-and-fields_en.html

C. Restart the simulation and locate an electric dipole, a positive charge of 5 nC and another of -5nC on the same straight line, separated by 1 grid, append the obtained image showing the intensity and direction of the electric field, draw 5 equipotential surfaces around each charge, and test with a field sensor moving it on an equipotential surface then indicate what you observed and what concludes in this situation.

D. Restart the simulation and locate different continuous positive charges along a horizontal straight line trying to form an infinite charge line. Attach with your report the image obtained showing the intensity and direction of the electric field, also from your results what can you conclude.

E. Restart the simulation and locate different continuous positive charges formed by a half-circle diameter circle trying to form a ring or circular distribution of positive charge. Attach with your report the image obtained showing the intensity and direction of the electric field inside and outside the charge distribution, also from your results what can you conclude.
