如图所示，两根水平平行固定的光滑金属导轨宽为L，足够长，在其上放里两根长也为L且与导轨垂直的金属棒ab和cd，它们的质量分别为2m、m，电阻阻值均为R（金属导轨及导线的电阻均可忽略不计），整个装置处在磁感应强度大小为B、方向竖直向下的匀强磁场中．

(1)现把金属棒ab锁定在导轨的左端，如图甲，对 cd施加与导轨平行的水平向右的恒力F，使金属棒cd向右沿导轨运动，当金属棒cd的运动状态稳定时，金属棒cd的运动速度是多大？

(2)若对金属棒ab解除锁定，如图乙，使金属棒cd获得瞬时水平向右的初速度v₀，当它们的运动状态达到稳定的过程中，流过金属棒ab的电量是多少？整个过程中ab和cd相对运动的位移是多大？
