A potential difference, applied between the ends of a conductor of uniform radius 2 mm, results in an electric field 300 V/m along the length of conductor. If current in the conductor is 4 A, resistivity of the material of conductor is nearly :

• A

  $2.8 \mathrm{x} {10}^{-6} \mathrm{\Omega }-\mathrm{m}$

• B

  $11.6 \mathrm{x} {10}^{-6} \mathrm{\Omega }-\mathrm{m}$

• C

  $9.4 \mathrm{x} {10}^{-4} \mathrm{\Omega }-\mathrm{m}$

• D

  $16.5 \mathrm{x} {10}^{-5} \mathrm{\Omega }-\mathrm{m}$
