Drift speed of electrons, when $1.5A$ of current flows in a copper wire of cross section $5mm2$, is $v$. If the electron density in copper is $9\times 10^{28}/m^3$ the value of $v$ in $mm/s$ is close to (Take charge of electron to be $=1.6\times 10^{-19}C$)

Assume that each atom of copper contributes one free electron. The density of copper is $9gc{m}^{-3}$ and atomic weight of copper is $63$. If the current flowing through a copper wire of $1mm$ diameter is $1.1$ ampere, the drift velocity of electrons will be:-
