A "gauge 8" jumper cable has a diameter d of 0.326 centimeters. The cable carries a current I of 30.0 amperes. The electric field E in the cable is 0.062 newtons per coulomb.
What electric field would have been required to create a current of 30.0 amperes in a copper "gauge 10" wire with diameter equal to 0.259 centimeters?
Express your answer in N/C. Use three significant figures.
