10.研究光电效应现象的实验装置如图甲所示,单色光的频率ν与该金属逸出的光电子的最大初动能Ek间关系图像如图乙所示。用光子能量为6.60eV的紫外线照射到光电管上阴极K,发生了光电效应。调节滑片P,当电压表的示数为2.46V时,电流计的示数恰好为零。已知光电子的电荷量大小为,e,普朗克常量h=4.1410^-15eV5。则下列说法正确的是A.屏的数值为1.010^15B.当电源左端为正极时,若增大人射光的频率,要使电流计的示数为零,滑片.P应向右调书C.当电源右端为正极时,电流计示数为零,则增大该入射光的光强,电流计会有示数D.当电源右端为正极时,若电流计有示数,则流过电流计的电流方向由上到下

15.(16分)如图,光滑平行导轨abc和cg固定在绝缘水平面上,导轨间距为L,其中ab、ef倾斜且与水平面的夹角为8,a、e两端之间连接一电容为C的电容器,abfe平面处在垂直于该平面向上的匀强磁场中,磁感应强度大小为B。bc、g水平放置,其中O1O2O3O4矩形区域存在竖直向上的匀强磁场,磁感应强度大小也为B,在两端之间连接一阻值为R的定值电阻且距离O2O3足够远,两导轨在处均平滑连接,bO1和fO4之间的导轨用绝缘材料制成,导轨的其他部分用金属材料制成,且电阻不计。三根长度均为L、阻值均为R的金属杆P、M、N垂直导轨放置、M、N静止在水平导轨磁场区域的左侧现使P从倾斜导轨上离水平面高为h处由静止释放,此后P与M、M与N间发生碰撞,且均为弹性碰撞。已知N的质量为m,P的质量为4m,,重力加速度为g,杆在运动过程中始终与导轨垂直且接触良好。(1)求P与M碰撞前瞬间的速度大小,(2)要使N获得的速度最大,杆M的质量应为多大?(3)在(2)问的前提下,若在O1O2O3O4区域中只能有一根杆在运动,且杆M恰好运动到O2O3处(没有磁场)并静止,则金属杆M、N从左向右通过右侧磁场过程中产生的总热量为多少?

10.如图所示,在边长为L的正方体ABCD-A'B'C'D'顶点上分别固定等量点电荷,电荷量均为Q。其中D与D'为负电荷,其他均为正电荷,位于BD'点,位电荷,,电荷量均假如将试探电荷从从AA中试探电荷所受合力为F,假如将试探电荷从AD中点移动到A′D'的中点,电场力对试探电试探连线中点的O处电荷量为+q的A'D荷做功为W,则关于所受的合力F和电场力对试探电荷做的功W,以下判断正确的是功的中点,电场力对试+q合力式探电正确的是A.F=166kgQ3L^2,沿BD方向沿BD方向D.W=0D.W=0
