Calculating the Force Exerted on a Point Charge by an Electric Field By: Courtney DuBois


The electric field has 3 point charges, positive charges, negative charge of equal magnitude, and a even larger negative charge. Total electric field is the vector sum of the individual fields created by each charge. Electric fields from multiple charges are more complex than those of single charges. Charges that go in the same direction add together to make a even higher charge. Charges that are unalike at a large distance subtract into a smaller charge, and are weak charges. Conductors and insulators generate large static charges and make into high voltage.


*Screening: the presence of other charges in the cell. *Polar molecule: 10 electrons tend to remain closer to the oxygen nucleus than the hydrogen nuclei. *Dipole: two centers of equal and opposite charges. *Coulomb interaction: two centers of the charge will terminate some of the electric field lines coming from a free charge (as on a DNA molecule), reducing the strength. *Xerography: a dry copying process based on electrostatics. *Photo conductor: Selenium, a substance with an interesting property, Senelium is an insulator when in the dark, and a conductor when in the light. *Aluminum Drum: when a negative charge is induced under the thin layer of uniformly positively charged senelium. *Laser printers: use the xerographic process to make a high quality image on paper.


Electric field: = F / q, rearranged to F = qE
