A 57.0 m length of coaxial cable has an innerconductor that has a diameter of 2.58 mm and carries a charge of8.10 µC. The surrounding conductor has an inner diameter of7.27 mm and a charge of -8.10 µC.
(a) What is the capacitance of this cable?
C = 1 nF
(b) What is the potential difference between the two conductors?Assume the region between the conductors is air.
ΔV = 2 kV
