strongest. Explain why this location is the strongest electric field.

8. Set up the simulation in a configuration similar to the grid below, turning on the Grid tool. Set one positive charge at the location of one of the circles. Set a negative charge at the location of the other circle. Then use the simulation to map out the electric field lines due to these charges on the grid provided below. If using Word to fill out the Lab, you can use InsertShapesLines/Arrows for this part.

Reflection Questions

1. Describe the general properties of the electric field you have drawn.

2. Does the electric field generally point away from the positive charge and towards the negative charge? Explain this in terms of the electric field.

3. Is the magnitude of the electric field, along a line connecting the two charges, bigger near the positive charge or the negative charge? Explain. Is the difference, if any, significant? Why or why not?

Electric Fields 1. Place one positive charge in the middle of the screen as shown below. 2. Calculate the electric field at a distance of 1m from the charge using the equation kq E = , 72, where k=8.98x109 N*m2/C2 3. Make sure the following settings are turned on: Electric Field Direction only Voltage Values Grid 4. Use sensors to measure the electric field a distance of 1m from the charge. a. How does this electric field value compare to your calculation in (2)? Reminder: 1 N/C = 1 V/m b. Calculate the electric field 2m away from the charge, then measure the electric field with the senor. How does this value compare? c. Calculate the electric field 3m away from the charge, the measure the electric field with the sensor. How does this value compare? = Print Layout Headings Edit Share Read Aloud O2:08 Call 89% c. Now turn on the Electric Field in settings. Give a few observations of the direction of the electric field. Check the arrows and compare your calculations and previous measurements for accuracy. Were they correct? d. Move around the sensor to find where the electric field is strongest. Explain why this location is the strongest electric field. 8.
