A wire AB is carrying a steady current of `12A` and is lying on the table. Another wire CD carrying current `5A` is held vertically above AB at a height of 1mm. Find the mass per unit length of the wire CD so that it remains suspended at the position when left free. Give the direction of the current flowing in CD with respect to that in AB. `g=10ms^-2`.

To solve the problem, we need to find the mass per unit length of wire CD so that it remains suspended when left free. We will also determine the direction of the current in wire CD with respect to wire AB. ### Step-by-Step Solution: 1. **Identify the Given Values:** - Current in wire AB, \( I_1 = 12 \, \text{A} \) - Current in wire CD, \( I_2 = 5 \, \text{A} \) - Height between the wires, \( R = 1 \, \text{mm} = 1 \times 10^{-3} \, \text{m} \) ...
