$A$ current of $1.6\, A$ is flowing through a wire having a cross-sectional area of $1\, mm^2$. If the density of free electrons in the material of the wire is $10^{29}\, m^{-3}$,the drift velocity of the electrons will be:

  • A
    $10^{-4}\, m/s$
  • B
    $10^{-3}\, m/s$
  • C
    $10^{-2}\, m/s$
  • D
    $0.1\, m/s$
