Two parallel vertical metallic rails AB and CD are separated by 1m.  They are connected at the two ends by resistances R1 and R2 as shown.  A horizontal metallic bar L of mass 0.2 kg slides without friction, vertically down the rails under the action of gravity.  There is a uniform horizontal magnetic field of 0.6 T perpendiculars to the plane of rails.  It is observed that when the terminal velocity is attained.  The powers dissipated in R1 and R2 are 0.76 W and 1.2 W respectively.  Find the terminal velocity of the bar L and the value of R1 and R2.
