Electricity, Magnets, & Circuits

  1. Oct 18, 2008 #1
    1. The problem statement, all variables and given/known data

    Part A- Charges and Fields
    1. Click on the category named Electricity, Magnets, & Circuits, then find Charges and Fields, click on it, then select Run Now!. (You may need to install Java onto your computer)
    2. Select Grid and Show Numbers in the green menu box. Place equal and opposite charges exactly 2 meters apart.
    3. Now place 3 E-field sensors on the grid; A) one exactly between the 2 charges, B) another 1 m above the first, and C) a 3rd anywhere on the grid that produces a net field vector at 45 degrees.
    4. Use the Print Screen key to take a picture of your set up.

    5. For each position A, B, and C, show calculations of the net E-field vector (size and direction) that closely matches the computer results. (Note: The units shown are V/m; don’t worry because 1 V/m is the same as 1 N/C.). Show your work directly on a separate sheet

    2. Relevant equations

    3. The attempt at a solution
    the question that I am asking is that what equations should I use because I am extremely confused

    This is an electrostatic problem involving point charges, so perhaps you could make use of the basic equations relating to electrostatics...
