A current of 10 amp is passing through a metallic wire of cross sectional area `4xx10^(-6)m^(2)`. If the density of the aluminium conductor is 2.7 gm/cc considering aluminium gives 1 electorons per atom for conduction fiind the drift speed of the electrons if molecular weight of aluminium is 27 gm.
