Physics 30: Assignment 4 10 6. A student wanted to determine the relationship between the electric field strength and distance 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 1050 750 Field strength (1014 NIC 10 - 10D 200 300 400 600 Distance of test charge (ml 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) Complete the data table showing the modified manipulated variable (1 mark)b) Graph the manipulated data showing a linear slope (4 marks)
