Question.4761 - Pre-Lab QuestionsHow are electric potential and electric field similar? How are they different?Draw the equipotential lines for a single, positive, charge.If you were to walk on an equipotential line, how would your electric potential change over time?What does it mean when equipotential lines are closer together? What does it mean when they are farther apart?What direction do electric fields travel?How can you tell from an electric field map whether an electric field is strong or weak?What would the electric field lines look like if the electric field was constant?Can there be a point in space where there is an electric potential but not electric field? Can there be a point in space where there is an electric field but no electric potential? Explain you answer. Use Figure 5 to answer the following questions:Figure 5: Charged particles P (left) and Q (right).Are charges P and Q negative or positive? How do you know?Which particle has the highest magnitude of charge? How do you know?Given the two field maps below, if the left charge (blue rectangle or circle) is positive and the right charge is negative, predict the electric field lines by drawing them over the field maps.Experiment 1: Mapping electric potentials-95253279775a.00a.Post-Lab Questionsa.a.30765752905760b.00b.b.b.Use the data collected to draw your equipotential lines on Figures 10a and 10b (above). Label what potential each equipotential line represents. Your instructor may require you to submit a photograph or scanned copy of your drawings.Add electric field lines to the Figure 10 field maps. Donât forget that electric fields are vectors and need to have a direction. Your instructor may require you to submit a photograph or scanned copy of your drawings.Hint: Use a different colored writing utensil to help make the distinction between the equipotential lines and the electric field lines.Did your predictions from Pre-Lab Question 10 match with your data analysis? Use your results to support your answer.Experiment 2: DESIGN YOUR OWN EXPERIMENTFigure 11: Blank equation mapping areas.
