What is the capacitance per unit length of a cylindrical capacitor (in pF/m), if the ratio of the radii of the two cylinders is 22.2?

Consider a cylindrical capacitor, with outer radius $R$ and cylinder separation $d$. Determine what the capacitance approaches in the limit where $d \ll R$. (Hint: Express the capacitance in terms of the ratio $d / R$ and then examine what happens as the ratio $d / R$ becomes very small compared to $1 .)$ Explain why the limit on the capacitance makes sense.
