SUMMATIVE: Electric Field Lab

Using the charges and fields simulation Links to an external site., collect data to show the proportional relationship between Electric Field Strength (Force/Charge or Newton/Coulomb), distance (r, in meters) and charge (q, in Coulombs).

Note: A Newton per Coulomb is equivalent to a Volt/meter. Also, a nano Coulomb, nC is equal to 10^-9 Coulombs.

Your primary deliverable will be two graphs, which show the relationship between Electric field strength and r, and electric field strength and q.

Your INDIVIDUALLY SUBMITTED AND CREATED lab report should include:

Title - Name of study/lab, with your name
Abstract - What is the point of this lab? What variables are we investigating? What is a one sentence description of the results/relationships observed?
Methods - What is the set up? What procedure did you use to collect data and measure variables? Describe tools, equipment and process. In each experiment, describe what you changed, what you kept constant, and how you measured/collected data. 
Results (graph!!) - Include your beautiful, properly labeled and scaled graphs. You should have two graphs. Electric Field vs Charge, and Electric Field vs distance. 
Analysis - What is the relationship between electric field strength, amount of charge, and distance away from electric field source? Create a math model, with relevant units and variables (do not use x and y!!!!). What does the slope/coefficient represent in each graph? What are its units?
Hint: Coulomb's constant is 8.99*10^9 Nm^2/C^2, or 8.99*10^9 Newton-meters^2/Coulombs^2, or Force-distance^2/charge^2. Since it is a constant, this would be the slope/coefficient from one or both of your graphs. Complete a percent-error calculation for slope/coefficient. % error = (experimental value - theoretical value)/theoretical value x 100. 
What is the vertical intercept, and if significant, what does it represent? (5% rule can be used to discard a small but non-zero intercept value. You MUST explain conceptually why you think a intercept should be zero, in additional to the 5% rule). Is intercept < 5% of your maximum measured dependent variable?
Conclusion - Based on your math models, what is the general form equation linking electric field to coulomb's constant (k) AND distance (r) AND charge (q) (combine your proportionalities together). 
E = math model including k, r and q.
