Physics 30: Assignment 4 10 A student wanted to determine the relationship between the electric field strength and distance (5) 6. of a test charge from the source charge. The data is recorded in the table below. Distance of a test charge from Electric field strength a source charge (m) (x 10' N/C) 100 90.0 200 22.5 300 10.0 400 5.60 500 3.60 600 2.50 The student then graphed the data: Field strength vs. distance of test charge 100.0 75.0 50.0 Field strength (x1094 NIC) 25.0 0.O 100 200 300 400 500 600 Distance of test charge (m) Use the curve straightening strategies found on the Physics 30 workbook p. 5 to demonstrate that the relationship between the electric potential and the distance is an inverse squared relationship. Your answer should include a data table showing the modified manipulated variable data and a graph showing the linear slope. wer: Manipulated variable! Respending variable . my
