A 7.2 mm diameter conducting wire carries a current of 3.8 A. If the density of the conduction electrons (free electrons) in the wire is n=19.6×1028m-3, determine the magnitude of the drift velocity of the electrons within the wire. Express your answer in units of μm/s (micrometers per second) using one decimal place. Take the charge of the electron e=1.6×10-19C.
