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 ?

Explanation

To solve the problem of how the mobility of electrons in a conductor changes when the potential difference is doubled while keeping the length and temperature constant, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Electron Mobility**:
- Electron mobility (μ) is defined as the drift velocity (vd) of electrons per unit electric field (E).
- Mathematically, this can be expressed as:
\[
