10.如图所示,电子连续不断、均匀地从电子枪的K极无初速度地逸出,经电压为U0的加速电场加速后,从A极上的小孔进入两正对的平行极板间,小孔处在平行极板正中间行极板间的距离为d、长度为2d,两平行极板上施加u=33U0t(V的交变电压,电子质量为m、电荷量为e,不计电子间的相互作用,电子通过极板间的时间极短,可认为电场不变化,下列说法正确的是uADdKKA.在加速电场中K极的电势比A极的电势低ar=1&2mB.电子离开A极时的速度大小不仅与电压U0有关,也与A、K两极间的距离有关C.当t=6时进人极板区域的电子在极板区域发生位移的大小为为36dD.从极板区域离开的电子占总数的

(2)下表是该实验记录的数据,弹簧始终在弹性限度内,每个钩码的质量均为m=20g,,取g=9.8m/s^2。根据表中数据在图乙中作出弹簧弹力F与弹簧长度l的F-l图像,并通过图线确定该弹簧劲度系数为k=N/m(结果保留2位有效数字)。
