(1)调节R x =R ,释放导体棒,当棒沿导轨匀速下滑时,求通过棒的电流I 及棒的速率v 。

(2)改变R x ,待棒沿导轨再次匀速下滑后,将质量为m 、带电荷量为+q 的微粒水平射入金属板间,若它能匀速通过,求此时的R x 。

9.如图所示,在竖直平面内有一个“日”字形线框,线框总质量为m ,每条短边长度均为l 。线框横边的电阻均为r ,竖直边的电阻不计。在线框的下部有一个垂直“日”字平面方向向里的磁感应强度为B 的匀强磁场,磁场的高度也为l 。让线框自空中一定高处自由落下,当线框下边刚进入磁场时立即做匀速运动。重力加速度为g 。求:

(1)“日”字形线框做匀速运动的速度v 的大小。

(2)“日”字形线框从开始下落起,至线框上边离开磁场的过程中所经历的时间
