NOL PHY 202 Part I: Click on the simulation to start it on your computer. 1. Place a 1 at; (nano-Coulomb) positive charge in the test area. Grab a test charge (aka an E- Field Sensor) to observe the direction of the E-Field. The arrow direction of the E-Field sensor gives the direction and the length of the arrow of the E-Field sensor gives the magnitude of the force on a positive test charge at a given location. Observe the sensor's arrow as you drag it around the E-eld. 2. Replace the positive charge with a negative point charge. To remove charges or E-Field Sensors, drag them back into their box. By convention, electric eld points (away from A'owam') a positive charge and points (away from / toward) a negative charge. 3 pts (underline the correct answer) 3. As the sensor gets closer to a point charge, the electric eld strength created by the charge (increases/ decreases). 2 pts (underline the correct answer} 4. Click on Values and tape measure to measure E eld strength and the distances from a eldcreating charge to a test charge (aka E-Field sensor). The tape measure can be dragged to a specic distance and placed anywhere on the eld. Be as accurate as possible placing the (+) markers of the tape measure exactly on the center of the sensor and exactly on the center of the eld-creating charge. 5. Complete the table below using a single positive charge (+1 51g): Use the equipotential plotter to measure the potential at the given location. Make sure to place the + mark of equipotential plotter on the top of the location where you want to measure the electric potential and click the pencil button to draw the equipotential line. Add a screenshot of the simulation for E eld and electric potential at 100.0 cm location from the positive charge. 3 pts [Screenshot] Data and Data Analysis: it you are unable to get the exact distance please get the closest and include your distance in the first column. Write down the exact value that you read from the simulation. These are considered as measurements from the tool.

Turn on the Grid and place 1 nC of positive charge and 1 nc of negative charge 4.0 m (400.0 cm) apart. 2. Turn on the Show E-Field 3. Answer the following two questions. (a) Using the equipotential plotter (use your mouse to move it), start from the positive charge, plot lines of equal potential every 0.50 m (50.0 cm) between positive and negative charges. Record the potential on the equipotential line in the table below. 7 + pts Potential on Equipotential 15.7 6.1 2.4 0.15 -2. 1 -5.2 -12.3 line (V) (b) Include the screenshot of a map of equipotential lines based on 3(a) below. 3 pts [Screenshot] 4. Answer the following two questions. (a) What is the direction of the electric field between +1 0C and -1 nC (Hint: use test charge aka electric field sensor to determine)?
