6.如图甲所示,在真空中固定两个相同的点电荷A、B,它们关于x轴上的P点对称,在x轴上的电场强度E与坐标位置x的关系图像如图乙所示。若在坐标原点O由静止释放一个点电荷C(受到的重力可忽略不计),释放后它先沿x轴正方向运动。规定沿x轴负方向为电场度的正方向,则点电荷CA.带正电荷B.在x1处动能最大C.在x2处电势能最大D.将沿x轴做往返运动

18.(11分)双聚焦分析器是一种能同时实现速度聚焦和方向聚焦的质谱仪,其模型图如图甲所示.其原理图如图乙所示,电场分析器中有指向圆心O的辐射状电场,磁场分析器中有垂直纸面的匀强磁场.质量为;m、电荷量为q的离子被加速后,进入辐射电场,恰好沿着半径为R的圆弧轨迹通过电场区域后,垂直边界从P点进人14圆形磁场区域,PO1=d.之后垂直磁场下边界射出并从K点进人检测器,检测器可在O1M和O2N之间左右移动且与磁场下边界距离恒等于0.5d.已知圆弧轨迹处的电场强度大小为E.(1)求磁场的磁感应强度B的大小;(2)由不同离子组成的粒子束,以不同速度进入电场分析器后都能沿着半径为R的圆弧轨迹通过电场并从P点垂直进入磁场,粒子离开O1O2时与O1O2所夹锐角相同,若探测器能接收到的粒子中比荷qm的最大值与最小值之比为λ,求λ的值.

9.使用蓝牙耳机接听手机来电,其信号传输的示意图如图所示,已知可见光的频率范围是:4.210^147.810^14Hz,,则蓝牙通信的电磁波A.是蓝光B.波长比手机通信的电磁波短C.在真空中的传播速度大小为3.010^8m/sD.在真空中的传播速度比可见光传播的速度小
