a coaxial cable has inner conductor with radius of 0.8mm and the outher conductor with inside radius of 3mm and outside radius of 4 mm . the space between the conductors is filled with material having 2.3 dielectric constant and 18.0×10^6V/m dielectric strength.calculate the maximum potential difference this cable can with stand?
