Panel 1: Electric Field Two Point Observations The magnitude lowers when the sensor moves right of the negative and direction increases. As the sensor moves left and direction decreases, the magnitude decreases. Panel 2: Electric Field Two Lines Observations The direction lowers as the charges move closer and increases as they get further apart. The magnitude increases when the charges are closer and decrease when further. Photo 3: Two Point Charges Simulation

Mapping Equipotential Lines Using a Simulation Questions Change the font color to green when inserting your responses. Pay attention to formatting. 1. What is the relationship between voltage and the distance from charges? Reference Photos 3 and 4 in your answer. As voltage increases, the distance between the charges decreases, and vice versa. Voltage and distance are inversely proportional. 2. Describe how the electric field changes as it nears a charged object. Refer to Panels 1 and 2 in your answer. The length increases as it moves towards the charges, so strength of the electric field increase. 3. How do the results from Exercise 1 compare to the results of this exercise? Discuss why they are similar/different. Electric fields are able to be vectors and the first exercise shows a higher voltage on the vector lines closer to the charges. 4. Draw or use the simulation to recreate the charge distribution that creates the following equipotential lines. Upload the image to Photo 5.

Mapping Equipotential Lines Using a Simulation 5. Describe sources of error in your calculations for the magnitude of the electric field reported in Data Table 1. What could be done to reduce the error? (Hint: Repeat the calculation in Part 3 with two charges closer together and then with two charges farther apart.) If you repeat the calculations, it is clear that there is more error when the charges are further apart. To reduce error, place the charges closer....
