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