Question

4. In the diagram, the switch is initially open, and the conducting bar of mass $m$, length $L$, and resistance $2R$ is at rest in the uniform magnetic field. When the switch is closed, the bar begins to accelerate because of the magnetic force on it. Find the acceleration of the bar, in terms of $m$, $L$, $R$, the battery voltage $V_0$, and the magnetic field $B_0$.
