If the distance between two parallel current carrying wires is doubled, what is the force between them?

Explanation

To find the effect on the force between two parallel current-carrying wires when the distance between them is doubled, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Formula for Force Between Wires**:
The force \( F \) between two parallel current-carrying wires is given by the formula:
\[
F = \frac{\mu_0 I_1 I_2 L}{2 \pi D}
