Current Electricity

A current of \(2 \mathrm{~A}\) flows through a wire of cross-sectional area \(25.0 \mathrm{~mm}^{2}\). The number of free electrons in a cubic meter are \(2.0 \times 10^{28}\). The drift velocity of the electrons is __________ \(\times 10^{-6} \mathrm{~ms}^{-1}\) (given, charge on electron \(=1.6 \times 10^{-19} \mathrm{C}\) ).
