Two conducting rods inclined at $\text{'}\theta \text{'}$ angle from horizontal are kept parallel at separation $\text{'}l\text{'}$ to each other. A resistor of resistance $R$ joins the two rods at their topmost point. A metal bar of length $\text{'}l\text{'}$ is free to slide on the rods as shown in figure. on releasing from rest, the maximum speed that can be attained by the bar if a constant magnetic field $B$ exists vertically downwards, is
