Coulomb’s Law

Review textbook Chapter 16 which involves the vector nature of electric forces. In this simulation, the green, red, and blue charges are originally (i.e., at t = 0) at the vertices of an isosceles triangle. The green and blue are fixed in space and the red charge is allowed to move. Find the net Coulomb force (magnitude and direction) on the red object due to the green and blue charged objects after 1.00 s has elapsed.

  • This simulation can be downloaded from within your course under “PH221.Simulations”; its file name is “Net Coulomb Force.ip”.
  • Fill in the blanks in the Lab Answer Sheet at the end of this lab.
  • Submit this Lab Answer Sheet when all of the labs are completed.
    • These can be scanned and sent as pdf or picture files (e.g. tif, gif, etc.) or by any other method of your choice as long as the Answer Sheets are legible and translatable by Grantham University.

Run the simulation. You will use the data from the “Time” and “Position” measurement tables (red, green, and blue) to help in calculating individual electrostatic (Coulomb) forces and directions.

Finally, calculate the net Coulomb force, Fc and direction, on the red object after 1.00 s; fill in the blanks on the Lab Answer Sheet to be handed in at the end of this week.
