Calculate the magnitude of the force between two point charges of +1.6 x 10-19 C and -1.6 x 10-19 C, for a range of distances, from r = 0.090 nm to r = 0.18 nm in 0.010 nm steps.
Plot the results on a graph of magnitude of force F versus distance r. You must label the graphs with axis labels including units, and a title. Also choose an appropriate scale of the graph to show the data.
