1、.高二物理期中考试试题第 I 卷（选择题共 60 分）一、选择题（每小题4 分，共分.在每小题给出的四个选项中，有的小题只有一个选项正确，有的小题有多个选项正确.全部选对的得4 分，选不全的得2分，有选错或不答的得0 分，请将正确答案填涂到答题卡上）、真空中有两个点电荷Q1和 Q2，它们之间的静电力为F，下面哪些做法可以使它们之间的静电力变为1.5F A使 Q1的电量变为原来的2 倍，Q2的电量变为原来的3 倍，同时使它们的距离变为原来的2 倍B使每个电荷的电量都变为原来的1.5 倍，距离变为原来的1.5 倍C使其中一个电荷的电量和它们的距离变为原来的1.5 倍D保持它们的电量不变，使它们的距
2、离变为原来的2/3 倍、如图所示，电灯L1、L2上分别有“220V，100W”、“220V，40W”字样，那么A a、b 接 220V 电压时，L1、L2均能正常发光B a、b 接 440V 电压时，L1、L2均能正常发光C无论a、b 两端接多少伏电压，L1、L2都不可能正常发光；D无论a、b 两端接多少伏电压，L1肯定不能正常发光；、关于电源电动势，以下说法中正确的是A电源的电动势等于电源没有接入电路时两极间的电压，所以当电源接入电路时，电动势将发生变化B在闭合电路中，并联在电源两端电压表的读数是电源的电动势C电源电动势是表示电源将其他形式的能转化为电能本领大小的物理量D在闭合电路中，电源电
3、动势在数值上等于内外电压之和、关于磁场和磁感线的描述，正确的说法是A磁感线从磁体的N 极出发，终止于S极.B磁感线可以表示磁场的方向和强弱C沿磁感线方向，磁场逐渐减弱D因为异名磁极相互吸引，所以放入通电螺线管内的小磁针的极一定指向螺线管的极、已知+介子、介子都是由一个夸克（夸克u 或夸克 d）和一个反夸克（反夸克u或反夸克d）组成的，它们的带电量如下表所示，表中e为元电荷。+u d ud带电量+e e+e32e31e32e31下列说法正确的是A+由 u 和d组成B+由 d 和u组成C由 u 和d组成D由 d 和u组成、两根长直漆包线交叉放置并分别通以如图所示的电流，那么两根电流的磁场在导线平面
4、内方向一致的是A区域、B区域、C区域、D区域、如图所示电路，开关S闭合后，四个灯泡都正常发光，某时刻t，L4因灯丝烧断而突然熄灭，假设其它三灯丝都没烧断，则A L2变暗，L3更亮，L1不变B L1、L3更亮，L2变暗C L1更亮，L2、L3变暗DL1、L2、L3都更亮、如图所示，匀强电场方向竖直向下，在此电场中有a、b 两个带电微粒（不计微粒间的相互作用），分别竖直向上、竖直向下做匀速运动，则下列说法中正确的是A两带电微粒带异种电荷B两微粒所受的电场力等大、反向文档编码:CB8B8I1L2F5 HF2B1A5U7N9 ZD6B5Z2O3U10文档编码:CB8B8I1L2F5 HF2B1A5U7
