Q. Two long parallel wires, having zero resistance, are connected to each other by a battery of 1.0 V. The separation between the wires is 0.5 m. A metallic bar of resistance 10 Ω, placed perpendicular to the wires, moves on these wires. A uniform magnetic field of 0.02 T is acting perpendicular to the plane containing the bar and the wires. Find the steady-state velocity of the bar.
