A 57.40-pF cylindrical capacitor carries a charge of 1.740µC. The capacitor has a length of 1.400 ✕ 10−3m.
(a) What is the potential difference across the capacitor?
V
(b) If the radial separation between the two cylinders is 6.380 ✕10−4 m, what are the inner and outer radii of thecylindrical conductors? (Use 8.854 ✕ 10−12C2/(N · m2) for the permittivity of freespace. Give your answers to at least four decimal places.)
