7. Explore the field. Try different coordinates for P. On the sketch below, draw arrows to show approxi- mately the magnitude and direction of the field at each of the 12 points marked by dots in the diagram below. Use an approximate scale of 1.0 cm # 200,000 N/C. Label each vector with the magnitude of the field, in N/C, and the direction, in degrees. 10* (cm) -> x (cm) -5 10 15 Comment: Setting the spreadsheet up is not a trivial task, but once it's set up, you can easily find the electric field at any point that you want. You can use calculus to find the electric field created by relatively simple charge distributions, but for complicated or irregular shapes, numerical methods are often the only practical way to calculate the electric field
