Part 2: Graphing Exercise By looking at your measurements and the theory exercise, suggest a model (i.e. hypothesise) how electric potential varies with distance along the line joining the two electrodes near to the centre. Measure appropriate data and record it in the table below. Then use the Excel template 'linear plot with errors' to produce a graph to test your hypothesis. From the slope of your graph, quantify your findings. (Note you may need to limit the extent of your graph for best results. Record the details of your plan/results over the page and attach a printout of the graph).

Please explain how to do the following question
