2.如图所示，矩形区域ABCD的AB边的边长为L，E、F分别是AB、CD边的中点，在AEFD区域内有竖直向下的匀强电场，在EBCF区域内有垂直于纸面向里的匀强磁场（图中未画出），一个质量为m，电荷量为q的带正电的粒子以速度v0从A点水平向右射入电场，结果粒子从EF边进入磁场后，在磁场中的轨迹刚好与FC和BC边相切，已知电场强度的大小为E= ，不计粒子的重力，求：
3.某电流表的内阻在0.1Ω～0.2Ω之间，现要测量其内阻，可选用的器材如下：
A．待测电流表A1（量程0.6A）；
B．电压表V1（量程3V，内阻约2kΩ）
C．电压表V2（量程15V，内阻约10kΩ）
D．滑动变阻器R1（最大电阻10Ω）
E．定值电阻R2（阻值5Ω）
F．电源E（电动势4V）
G．电键S及导线若干
①电压表应选用{#blank#}1{#/blank#}；（填“V1”或“V2”）
②在右面方框内画出实验电路图；
③如测得电压表的读数为U，电流表的读数为I，则电流表A1内阻的表达式为：RA={#blank#}2{#/blank#}．
4.如图所示，滑块A的质量m=0.01kg，与水平地面间的动摩擦因数μ=0.2，用细线悬挂的小球质量均为m=0.01kg，沿x轴排列，A与第1只小球及相邻两小球间距离均为s=2m，线长分别为L1、L2、L3…（图中只画出三只小球，且小球可视为质点），开始时，滑块以速度v0=10m/s沿x轴正方向运动，设滑块与小球碰撞时不损失机械能，碰撞后小球均恰能在竖直平面内完成完整的圆周运动并再次与滑块正碰，g取10m/s2，求：
6.2016年，某国宏观经济形势如下：产能利用率不足；固定资产投资同比下降4.0%；居民消费价格指数（CPI）增幅从2.5%下跌至1%，低于国际公认的合理值3%。据此，预防通货紧缩成为关注的焦点。若不考虑其他因素，可能引发通货紧缩的传导路径是（ ）
①产能过剩→工业品供过于求→工业品价格走低→企业利润下滑
②消费低迷→消费品供过于求→消费品价格走低
③社会总供给大于社会总需求→物价总水平持续下跌
④企业投资萎缩→失业率上升→居民收入下降
