Question 11 / 1 ptsA uniform conducting rod of length 15 cm has a potential difference across its ends equal to 34 mV (millivolts). What is the magnitude of the electric field inside the conductor in units of N/C? (Reminder: NEVER include units with ANY submission to a numerical question.) Question 21 / 1 ptsA cylindrical rod has a length of 73 cm and a diameter of 1.2 mm. What is the cross-sectional area in 10-6 m2?Do not include units with your answer.
