To solve the problem regarding how the drift velocity is affected when the potential difference \( V \) is doubled and the length \( l \) is halved, we can follow these steps:
### Step-by-Step Solution:
1. **Understand the relationship of drift velocity**:
The drift velocity \( v_d \) of charge carriers in a conductor is given by the formula:
\[
v_d = \frac{eE}{m\tau}
