The area of cross-section, length and density of a piece of a metal of atomic weight `60` are `10^-6 m^2`, `1.0 m` and `5xx10^3 kg//m^3` respectively, every atom contributes one free electron. (Given Avogadro number =`6xx10^23//mol`). Find the drift velocity of electrons in the metal when the current of `16A` passes through:
