7.5 Exercise 9

A very large sheet of insulating material has had an excess of electrons placed on it to a surface charge density of $–3.00 \text{nC}/\text{m}^{2}$. (a) As the distance from the sheet increases, does the potential increase or decrease? Can you explain why without any calculations? Does the location of your reference point matter? (b) What is the shape of the equipotential surfaces? (c) What is the spacing between surfaces that differ by 1.00 V?
