POST LABORATORY QUESTIONS 1. Where is the electric field magnitude the greatest - is it where the lines of force are closely packed or where they are more spread out? Please explain your reasoning referring to the electric field lines that you have generated, possibly in terms of the equipotential lines in different regions. 2. Can two equipotential lines cross each other? Explain in terms of the implications of such a crossing on the voltage value at that point. 3. Can two electric field lines cross each other? Explain in terms of the force experienced by a charge placed at such an intersection. 4. Is the boundary of a conducting surface an equipotential? Explain. At what angle will the electric field lines enter or leave the conductor edge in your experiment? 5. If a negatively charged particle is placed on an electric field line, in which direction will it tend to move compared to the direction of the field lines? How is the answer different for a positively charged particle? Explain. 6. Determine the force vector (magnitude and direction) on an electron placed on one of the two regions for which you calculated the electric field strength. What is the change in potential energy of the electron as it moves from one equipotential line to another of higher potential value by 2.0 V. (The charge of an electron is -1.60 x 10-19 C) 7. If the electron is replaced with a proton in post-lab 6, how does the answer change? Explain.
