ARE WE REAL 29. An electron is travelling at 100 km/s parallel to a long straight horizontal conductor a distance of 3.00 cm from the conductor. A current of 12.0 A runs through the wire as the electron travels parallel to it, in the same direction as the electron's velocity. Find the strength of the external electric field that will prevent the elec- tron from deviating from its original path. Express your answer in V/m. n
