Copper has `8.0xx10^(28)` conduction electrons per `metre^3`. A copper wire of length 1m and cross sectional area `8.0xx10^(-6)``m^2` carrying current and lying at right angle to a magnetic field of strength `5xx10^(-3)` T experiences a force of `8.0xx10^(-2)N`. Calculate the drift velocity of free electrons in the wire.
