Name Lab 8 - Graphing Electric Field Relationships Open the Charges and Field Simulation ( https://phet.colorado.edu/en/simulation/charges-and- fields ). In this simulation the little yellow "E field sensors" are used to measure the electric field at specific points when a charged "molecule" (positive or negative sign) is dragged onto the screen. You can collect data by turning on "Values" & utilizing the tape measure. Each "molecule" has a charge of +1 nC and they can be layered to create a larger charge. Determine the relationship between each of the variables by graphing the data from each of the experiments below using the best fit line if straight or best fit curved line if a distinct curve is present. Use the graphed line to determine if the relationship is direct / linear, exponential, or inverse. Graphs should be fully labeled. a. Determine the relationship between amount of charge (nC) and the strength of the electric field (V/m) around a charged body using the tape measure to determine Im. Keep the distance constant and vary the amount of charge by adding charges in the same place. Collect data and plot a graph of E-Field vs. charge below. (5 marks) Calculate the slope
