Need help with this one please thank you;)
Part 1: Mapping and estimating E fields through Equipotentials: Explore the E field between two parallel plates using the voltage probes You'll use the Charges and Fields PhET lab (https://phet.colorado.edu/sims/html/charges-and- fields/latest/charges-and-fields_en.html) for this activity. It isn't quite the same as the on-campus experiment, with actual power supplies and charge distribution sheets, but the concepts are similar. a) Start up the sim, click on the GRID and VALUES boxes, and create a simple dipole with two charges separated by -2 m. You can use the tape measure tool to verify the distance between the charges. b) Drag the Equipotential indicator over the space between the charges, and explore the values at different distances directly between the points. Record those in a spreadsheet. Distance Distance from + Voltage from + Voltage charge charge c) Using the indicator to explore the voltage around the space between the charges above and below the line between, and the ruler to measure the distances from the positive charge to a test point. Look for points in the space that have the *same" voltage. Record at least 20 points, above and below the center line between the charges. ->Make a sketch of your test points on graph paper, and record the voltage for each point. d) On your graph paper: Connect points of equal potential into equipotential lines, using a colored pencil or pen. In a different color, show lines of the (assumed) uniform E field between the plates that produced the equipotential lines. These E field lines will be perpendicular to the equipotential curves you have connected. Now explore the E field for a "uniform" distribution of charges. Drag at least 15 positive and 15 negative charges onto the screen, in two vertical (or horizontal) rows at least I meter apart, and as closely and evenly spaced as possible. Your goal will be to create a "uniform" E field between the charge distributions, much like the field between two charged plates. Use the Equipotential probe to explore the voltage at spots between the two rows of charges, and capture those values in another spreadsheet. Distance from + Voltage charges Make another sketch on graph paper, use colored pencils to again connect and identify equipotential lines and E fields. Be sure to label your sketch so that each set of lines is clearly identified. From the values you have recorded, determine the strength of the E field in Volts/meter between the plates, and indicate in your sketch over what area that strength is relatively constant. -2 E field strength between the plates: (Volts/Meter) In addition to your data tables and labeled sketches which you can photograph and upload, please also answer the following questions: How many points do you think you should record for each voltage reading? 1i. How many different voltage readings should you record? iii. How does the number of points that you collect affect the precision of your calculated values of the E field? iv. How many significant figures, and with what uncertainty, should those values be reported? Defend your choices
