Your radio station needs a new coaxial cable to connect the transmitter and antenna. One possible cable consists of a 2.0mm diameter inner conductor and an outer conductor with diameter 1.6cm and negligible thickness (see the figure); the maximum safe potential difference between the conductors is 2 kV. In your application, the conductors carry charge densities (plus or minus)62 nC/m.Will this cable work for you?
