7. The potential difference between electrical charges is inversely proportional to the square of the distance between the charges. The potential difference also depends on the size of the charges, but we'll keep the charge size the same in this question. For two charges the potential energy between them is 9 Nm²/C² at a distance of 100 m. a) Determine an equation that relates the potential difference between the charges to the distance between them. b) Using the same charges, what is the potential difference if they are moved to a distance. of only 12 m apart?
