A potential difference of \( 10 \mathrm{~V} \) is applied across a conductor of length \( 0.1 \mathrm{~m} \). If the drift velocity of electrons is \( 2 \times 10^{-4} \mathrm{~m} / \mathrm{s} \), the electron mobility is:
(A) \( 1 \times 10^{-6} \)
(B) \( 2 \times 10^{-6} \)
(C) \( 3 \times 10^{-6} \)
(D) \( 4 \times 10^{-6} \)
