139817 In the experiment of \(\mathrm{Ohm}\) 's law, a potential difference of 5.0 V is applied across the end of a conductor of length \(10.0 \mathrm{~cm}\) and diameter of \(5.00 \mathrm{~mm}\). The measured current in the conductor is \(2.00 \mathrm{~A}\). The maximum permissible percentage error in the resistivity of the conductor is
