A metal wire of length l is connected to an ideal battery of emf V and it is found that drift velocity acquired by the electrons is `v_(d)`. If the same wire is stretched to double its length then what will be the drift velocity of electrons?

Explanation

To solve the problem, we will analyze how the drift velocity of electrons changes when the length of the wire is doubled.

### Step-by-Step Solution:

1. **Understanding Drift Velocity**:
The drift velocity \( v_d \) of electrons in a conductor is given by the formula:
\[
v_d = \frac{E \tau}{m}
