To solve the problem, we need to find the ratio of the drift velocities of electrons in two wires, X and Y, which are connected in series across a battery. We know that the number density of electrons in wire X is twice that in wire Y.
### Step-by-Step Solution:
1. **Understand the Relationship**:
The drift velocity (V_d) of electrons in a conductor is given by the formula:
\[
V_d = \frac{I}{n \cdot A \cdot e}
