7. The potential difference between electrical charges is inversely proportional to the square ofthe distance between the charges. The potential difference also depends on the size of thecharges, but we'll keep the charge size the same in this question. For two charges the potentialenergy 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 thedistance between them.b) Using the same charges, what is the potential difference if they are moved to a distanceof only 12 m apart?

We are given that the potential difference depends on size of charges. The potential difference is…
