Two vertical mettalic rails are seperated by 1 m . They are connected by R1 and R2 as shown . A horizaltal bar of l=1m and m= 2kg slides smoothly down.Magnatic field exists as shown in the diagram. The bar is realeased and it is seen that when terminal velocity is attained , power dissipiated in R1 and R2 are 0.76 and 1.2 watts respectively. Find terminal velocity and R1 and R2.
