Videо Respоnse Questiоn Electric Potentiаl, Electric Potentiаl Energy, аnd Electric Field Instructions:This question will be answered verbally. HonorLock will automatically record a video as you complete this exam. When you reach this question, respond out loud to the prompts below. Speak clearly and concisely. You may reference the data table and equipotential map from the lab. Try to keep your full response under 3 minutes. Use the example lab below to answer the prompts that follow! Example Lab Mapping Electric Potential, Electric Field, and Electric Potential Energy Objective To experimentally investigate the relationship between electric potential (V), electric field (E), and electric potential energy (U) by mapping equipotential lines and using them to infer the electric field. Experimental Setup Conductive paper Two electrodes connected to a DC power supply Voltmeter Ruler or grid overlay Power supply set to a fixed voltage difference Common electrode configurations: Parallel plates Point–plate configuration Procedure Connect the electrodes to the power supply and apply a fixed voltage difference. Use the voltmeter to measure electric potential at various positions between and around the electrodes. Record position and corresponding potential values in a data table. Identify and sketch equipotential lines based on equal potential measurements. Use the spacing of equipotential lines to qualitatively infer the electric field. Consider the behavior of a positive test charge placed at different locations in the field. Data Collected Position (cm) Electric Potential (V) 1.0 18.0 2.0 15.2 3.0 12.5 4.0 9.9 5.0 7.4 Prompt In this lab, you mapped electric potential and used those measurements to understand the electric field and electric potential energy. In your response, explain how electric potential, electric field, and electric potential energy are connected, using evidence from the lab. Your explanation should include: Electric potential and electric potential energy:Explain how electric potential is related to electric potential energy and describe the role of the charge of a particle. Electric field and electric potential:Explain how the electric field is related to changes in electric potential and how the equipotential map helps reveal the field’s direction and relative strength. Interpretation of the data:Describe how the spacing of equipotential lines or changes in measured potential with position indicate regions of stronger or weaker electric field. Motion of a charged particle:Describe what happens to the electric potential energy of a positive test charge as it moves in the direction of the electric field, and explain why. You do not need to perform calculations. Focus on conceptual understanding and physical reasoning.
