Physics A circuit contains one battery and two wires in series, as shown in the diagram. The two wires have different lengths and are made of different materials. Wire 1 is 15 cm long and is made of a material whose electron mobility is 3e-4 (m/s)/(V/m). Wire 2 is 9 cm long and is made of a material whose mobility is 1.2e-4 (m/s)/V/m). Both wires have a radius of 0.75 mm and approximately Be27 mobile electrons per cubic meter. The emf of the battery is 2.4 volts. A steady state current runs in the circuit. wire 1 wire 2 What is the magnitude of EA, the electric field inside wire 1 at location A, in V/m? O 16 O 6.4 O 13 O 10 O 1.5 24
