A long cable consists of an inner conducting cylinder of radius 0. 80 mm and an outer conducting cylinder of radius 4. 95 mm, with an insulating material with dielectric constant latex: \kappa = 5. 6 filling the space between them. If the conductors are held at a potential difference of 1 volt, how much energy is stored in 1 meter of this cable?.
