(a) Explain how the answer to Problem 55 would change if the surface were increased in size (expanded) by a factor of two. (b) How would the answer to Problem 55 change if three more electrons were placed inside the surface?

(reference problem 55)

Consider an electron and the surface that encloses it in Figure P17.55. What is the electric flux through this surface?
