Q)

When 5V potential difference is applied across a wire of length $0.1\;m$ , the drift speed of electrons is $2.5 \times 10^{-4}\;ms^{-1}$. If the electron density in the wire is $8 \times 10^{28}\;m^{-3}$, the resistivity of the material is close to :

$\begin{array}{1 1} 1.6 \times 10^{-7} \Omega m \\ 1.6 \times 10^{-6} \Omega m \\ 1.6 \times 10^{-5} \Omega m \\ 1.6 \times 10^{-8} \Omega m \end{array} $
