A current of 5 A is passing through a metallic wire of cross-sectional area \(4 \times 10^{-6} \mathrm{~m}^{2}\). If the density of charge carriers of the wire is \(5 \times 10^{25} \mathrm{~m}^{-3}\), the drift velocity of the electrons will be
- \(1 \times 10^{2} \mathrm{~ms}^{-1}\)
- \(1.56 \times 10^{-2} \mathrm{~ms}^{-1}\)
- \(1.56 \times 10^{-3} \mathrm{~ms}^{-1}\)
- \(1 \times 10^{-2} \mathrm{~ms}^{-1}\)
Answer
(C) 1.56 10^ -3 ~ms ^ -1
