Problem

Two conductors P and Q have electron mobilities of 5.0×10−3 m2 V−1 s−15.0\times10^{-3}\,\text{m}^2\,\text{V}^{-1}\,\text{s}^{-1} and 2.0×10−3 m2 V−1 s−12.0\times10^{-3}\,\text{m}^2\,\text{V}^{-1}\,\text{s}^{-1} respectively. Under the same applied electric field, which conductor will have the higher drift velocity of electrons? Give a brief reason for your answer.
