Two parallel horizontal conductors are suspended by two light vertical threads each 75 cm long. Each conductor has a mass of `40gm^-1`, and when there is no current they are 0.5 cm apart. Equal current in the two wires result in a separation of 1.5 cm. Find the values and directions of currents. Take `g=9.8ms^-2`.

To solve the problem step by step, we will analyze the forces acting on the conductors and apply the relevant formulas. ### Step 1: Understand the setup We have two parallel conductors suspended by threads. Each conductor has a mass of 40 g/m, and when no current flows, they are 0.5 cm apart. When equal currents flow through them, they repel each other and the separation increases to 1.5 cm. ### Step 2: Identify forces acting on the conductors 1. **Gravitational Force (Weight)**: The weight of each conductor can be calculated using: \[ ...
