Explanation:
Position where the orientation of the needle is independent of the magnitude of current:
- At a distance d/2 from any of the wires
Reasoning:
- When the magnetic needle is placed at a distance d/2 from any of the wires, the magnetic fields produced by the two wires are equal in magnitude and opposite in direction at that point.
- The magnetic fields due to the two wires cancel each other out at this position, resulting in a net magnetic field of zero.
- As a result, the orientation of the magnetic needle will be independent of the magnitude of current in the wires.
Conclusion:
- Therefore, at a distance d/2 from any of the wires, the orientation of the magnetic needle will be independent of the magnitude of current in the wires.

The magnetic force is given by F = q(v x B), where q = 3.5C, v = 2m/s and B = 4 units. Thus we get F = 3.5(2 * 4) = 28 units.
