This is based on example 25.1 problem. Assume the b following values to use after you have neatly shoed the derivation. b = 1.2a , and / = 1.0 cm. b a) Calculate capacitance C, b) derive and find AV and c) find charge Q. -QA solid cylindrical conductor of radius a and charge Q is coaxial with a cylindrical shell of negligible thickness and radius b > a. Find the capacitance of this cylindrical capacitor if its length is 0. Q. "3 \fb a - 1 2k In (bla b a Q -Q a bSuppose b = 2.00a for the cylindrical capacitor. You would like to increase the capacitance, and you can do so by choosing to increase either 0 by 10% or a by 10%. Which choice is more effective at increasing the capacitance? :Wm ( J 2kg mam) =1.16 C'_ ln(2.00a/a) _ 1112 C _ 111(2.00a/l.10a)_ 1111.82
