$2.$ Draw electric field lines $(25$ points$).$

Once you have your surface plots for both the point and line configuration and the parallel plate

configuration in Excel in step $1,$ you can create another copy of them, then change the chart type

to "Wireframe Contour", then print these wireframe contour plots and hand draws electric filed

lines on these plots. Please indicate on your drawings which lines are equipotential lines and

which are electric field lines. Take a picture of each of your drawings for submission. $($Note: For

drawing the electric field lines, if you don't like to work it on paper, you can save the wireframe

contour plots as images, and then you draw the electric field lines on the images using some

software available on your computer.$)$
