Here is the assignment link for the lab 6 https://gcccd.instructure.com/courses/54099/assign…
Here’s the assignment below and if you can’t understand it just click on the link above.
This week we shall use simulations to examine the behavior of electric fields around charges and conductors. One advantage of simulations is that there is virtually no experimental uncertainty, and another is that they allow us to visualize these invisible force fields.

Embed your answers in the textbox. Numbered items listed in green are for you to include in your submission. Make sure to identify each item with Part and Question numbers, e.g. “A6.”, etc.
Pro Tip: Write your answers to the questions in Notepad (Windows) or Textedit (Mac) and add your edited screenshots in those editors. Then copy/paste question-by-question into the Canvas answer box. Check your work before you submit!
To take a screenshot of an active window:
Windows: Win+SHIFT+S then click the preview to save.
Mac: Cmd+SHIFT+4, then space, then click) .
Chromebook or tablet: you’re on your own! Find a way.
(Note that using your phone to take a poorly composed picture of your computer screen is NOT acceptable for this activity and will not be graded!). Embed your images at “Medium” size in the text box, next to the numbered part/question.
Part A: Dipole field (5 points)
Use: https://phet.colorado.edu/en/simulations/charges-and-fieldsLinks to an external site.
Links to an external site.Check the Grid option
Un-check the Electric Field option
Drag a +1nC (⊕) and -1nC (⊖) charge into the main area like this:
Use 4 sensors to find 4 locations where the total E-field due to these charges is horizontal, with different magnitudes for each.
Embed the screenshot as a Medium sized image in the text entry window.
Part B: Equilateral triangle (10 points)
Clear the screen and arrange three -1nC (⊖) charges in an equilateral triangle like this. Make the base of the triangle at least 4 large squares in length. (You will need to do some trigonometry to place the third charge!):
Check the “Values” box and deploy 5 sensors to find and show 5 locations:
a. One where the total E-field is ZERO
b. One where the total E-field is pointing LEFT
c. One where the total E-field is pointing RIGHT
d. One where the total E-field is pointing straight UP
e. One where the total E-field is pointing straight DOWN
Take a screenshot of the 3 charges + 5 sensors and embed it in the text box.
Only for the answer to “2c” above: Draw a diagram showing the 3 E-field vectors created by each individual charge, PLUS the total E-field. Use a ruler and graph paper if drawn by hand. Here’s an example (from a different charge configuration) that was made using MS Powerpoint. For hand-drawn diagrams, printable metric graph paper can be downloaded here.Download here.
Your vectors do not have to be to exact scale, but should show the direction and approximate relative strengths of the E-fields due to the 3 charges.
PART C: CONDUCTORS AND ELECTRIC FIELDS (5 POINTS)
For this part use: https://www.falstad.com/emstatic/fullscreen.htmlLinks to an external site.
Click on “Clear All”. Un-check the “Draw Equipotentials” option. (More about that next week!)
Set the Show setting is set to Show E/rho/j
Set the Mouse setting to Mouse = “Add – Conductor” (negative) to add a negatively charged conductor.
Use it to draw a 10 block x 10 block square in the middle of the screen
NOTE: The conductor has a net negative charge on it but the charge is able to move around. We shall learn that the charge on an empty conductor will move around to make the E-field inside it 0, regardless of what the external field is. (A “Faraday cage”.)
NOTE: Positive Charge is shown as YELLOW
NOTE: Negative Charge is shown as BLUE
Change the Mouse setting to be Mouse = Add – Draggable Charge (negative) to add a charge just below the square.
Using the 2 NOTEs above as a guide, describe in 2 or 3 sentences, how the charge is distributed around the exterior of your square conductor (Notice that the E-field inside the conductor is always 0).
Drag the point charge around and notice how the charge distribution changes in the square.
Take a screenshot of your setup with the point charge in a unique position, and embed it in the text box.
In a couple of sentences, describe how the charge distribution on the conductor changes as you move the draggable charge.
Clear the area and play around and make an interesting new setup using whatever Mouse Tools interest you. Use conductors and charges and investigate some configuration you design.
Take a screenshot and embed the image of your custom configuration.
Write a few sentences describing the behavior of the E-field around your conductors and charges.
