Find the mobility of electron in a wire, if its average collision time is 9.1 \times 10^{-15} {s}. (charge of electron =1.6 \times 10^{-19} {C} and mass of electron =9.1 \times 10^{-31} {kg} )

Correct Answer is : 1.6×10−3m2∕V−s

9.1 \times 10^{-3} {m}^2 \/ {V}- {s}

1.6 \times 10^{-3} {m}^2 \/ {V}- {s}

1.75 \times 10^{-3} {m}^2 \/ {V}- {s}

1 \times 10^{-3} {m}^2 \/ {V}- {s}
