Question
How does the mobility of electrons in a conductor change, if the potential difference applied across the conductor is doubled, keeping the length and temperature of the conductor constant?
✓

Answer

The mobility of electrons in a conductor is given by the expression,
$\mu=\frac{\text{eT}}{\text{m}}$
As it's independent of the applied potential difference, so it will not change if the applied potential difference will be doubled.
