Two parallel vertical metellic rails AB ...

Two parallel vertical metellic rails `AB` and `CD` are separated by `1m`. They are connecting at two ends by resistances `R_(1)` and `R_(2)` as shown in Fig. 3.96. A horizontal metallic bar `L` mas `0.2 kg` slides without friction vertically down the rails under the action of gravity. There is a uniform horozontal magnetic field of `0.6 T` perpendicular to the plane of the rails. It is observed that when the terminal velocity is attained, thwe power dissipated in `R_(1) and R_(2)` are `0.76 and 1.2W`, respectively. Find the terminal velocity of the bar `L` and the values of `R_(1) and R_(2)`.
