Electromagnetic Induction

The inductors of two LR circuits are placed next to each other, as shown in the figure. The values ofthe self-inductance of the inductors, resistances, mutual-inductance and applied voltages arespecified in the given circuit. After both the switches are closed simultaneously, the total work doneby the batteries against the induced EMF in the inductors by the time the currents reach their steadystate values is ______ mJ.
