In the arrangement shown in the figure when the switch S_2 is open, the galvanometershows no deflection for l = L/2. When the switch S_2 is closed, the galvanometer showsno deflection for l = 5/{12}L. The internal resistance of 6V cell, and the emf E of the otherbattery are respectively (internal resistance of cell of emf E is negligible)
