Two long parallel wires of zero resistan...

Two long parallel wires of zero resistance are connected to each other by a battery of `1.0V` . The separation between the wires is `0.5m` . A metallic bar, which is perpendicular to the wire and of resistance `10Omega` moves on these wire when a magnetic field of `0.02` tesla is acting perpendicular to the plane containing the wire and the wires. Find the velocity of the bar as a function of time if the mass of the bar is `0.002kg` . Find also the steady-state velocity of the bar.
