2011届高考第一轮总复习总分为练兵场第6章第一讲一、选择题1．法拉第首先提出用电场线形象生动地描绘电场，如下图为点电荷a 、b 所形成电场线的电场分布图，以下几种说法正确的答案是 ()A ．a 、b 为异种电荷，a 带电量大于b 带电量B ．a 、b 为异种电荷，a 带电量小于b 带电量C ．a 、b 为同种电荷，a 带电量大于b 带电量D ．a 、b 为同种电荷，a 带电量小于b 带电量[答案]B[解析] 由电场线分布情况可知a 、b 为异种电荷，b 处电场线比a 处电场线要密，故b 处附近场强大于a 处附近场强，b 带电量大于a 带电量，所以B 正确．2．将一质量为m 的带电粒子(不计重力)放在电场中无初速释放，如此如下说法正确的答案是()A ．带电粒子的轨迹一定和电场线重合B ．带电粒子的速度方向总是与所在处的电场线切线方向一致C ．带电粒子的加速度方向总是与所在处的电场线切线方向重合D ．带电粒子将沿电场线的切线方向抛出，做抛物线运动[答案]C[解析] 带电粒子的轨迹与电场线重合必须满足：①电场线是直线，②只受电场力，③v 0＝0或v 0方向与场强方向共线，所以A 错；带电粒子的速度方向不一定与E 方向一样，但其所受电场力的方向必与该处电场线的切线重合，应当选项B 错，C 对；因为电场不一定为匀强电场，其合力不一定为恒力，故不一定做抛物线运动，选项D 错．3．如下列图，实线为不知方向的三条电场线，从电场线中M 点以一样速度垂直于电场线方向飞出a 、b 两个带电粒子，运动轨迹如图中虚线所示，如此 ()A ．a 一定带正电，b 一定带负电B ．a 的速度将减小，b 的速度将增大C ．a 的加速度将减小，b 的加速度将增加D ．两个粒子的动能，一个增加一个减小[答案]C[解析] 带电粒子所受电场力的方向大致指向轨迹弯曲的内侧，如此可知a 、b 两粒子所受电场力方向大致为向左、向右．因不知电场线的方向，如此无法确定两带电粒子的电性，A 错误．电场力对两带电粒子均做正功，动能和速度均增加，如此B 、D 错误．电场线的疏密程度表示电场的强弱，且电场力F ＝qE ，a ＝F m，如此可知a 的加速度将减小，b 的加速度将增加，如此C 正确．4．(2010·镇江测试)如下列图，在真空中一条竖直向下的电场线上有a 、b 两点．一带电质点在a 处由静止释放后沿电场线向上运动，到达b 点时速度恰好为零．如此下面说法正确的答案是()A ．该带电质点一定带正电荷B ．该带电质点一定带负电荷C ．a 点的电场强度大于b 点的电场强度D ．质点在b 点所受到的合力一定为零[答案]BC[解析] 带电质点由a 点释放后向上运动，可知合力方向向上，而质点所受重力竖直向下，故电场力一定竖直向上，与电场线方向相反，可知该质点一定带负电，B 项正确，A 项错；带电质点到b 点时速度又减为零，可知向上运动过程中，合力先向上再向下，即重力不变，电场力减小，可知a 处电场强度大于b 处电场强度，C 项正确，D 项错．5．宇航员在探测某星球时发现：①该星球带负电，而且带电均匀；②星球外表没有大气；③在一次实验中，宇航员将一个带电小球(其电荷量远远小于星球电荷量)置于离星球外表某一高度处无初速释放，恰好处于悬浮状态．如果选距星球外表无穷远处的电势为零，如此根据以上信息可以推断 ()A ．小球一定带正电B ．小球的电势能一定小于零C ．改变小球离星球外表的高度并无初速释放后，小球仍然处于悬浮状态D ．改变小球的电荷量后再在原高度处无初速释放，小球仍然处于悬浮状态[答案]C[解析] 设星球和带电小球的质量分别为M 、m ，电荷量分别为Q 、q ，由于星球带电均匀，可看作电荷集中在球心的点电荷，释放小球后，小球受万有引力和库仑力而处于平衡，有：G Mm (R ＋h )2＝k (R ＋h )2可知：小球带负电，且平衡位置与高度无关，所以C 选项正确． 6．(2009·泰州模拟)如下列图，有一带电量为＋q 的点电荷与均匀带电圆形薄板相距为2d ，＋q 到带电薄板的垂线通过板的圆心．假设图中a 点处的电场强度为零，如此图中b 点处的电场强度大小是 ()A.kq 9d 2＋kqd2 B ．k q 9d 2－k q d 2 C ．0 D ．k qd2 [答案]A[解析] 由a 点处电场强度为零，可知带电圆形薄板在a 处的场强E 1与＋q 在a 处的场强E 2等大反向，故E 1＝E 2＝kq d 2；由对称性可知，带电圆形薄板在b 处的场强大小也为E 1，方向向左，而＋q 在b 处的场强E 2′＝kq (3d )2，方向也向左，故图中b 点处的电场强度大小为E 1＋E 2′＝kq d 2＋kq 9d2，故A 正确． 7．两个质量分别是m 1、m 2的小球，各用丝线悬挂在同一点，当两球分别带同种电荷，且电荷量分别为q 1、q 2时，两丝线张开一定的角度θ1、θ2，两球位于同一水平线上，如下列图，如此如下说法正确的答案是()A ．假设m 1>m 2，如此θ1>θ2B ．假设m 1＝m 2，如此θ1＝θ2C ．假设m 1<m 2，如此θ1>θ2D ．假设q 1＝q 2，如此θ1＝θ2[答案]BC[解析]m 1、m 2受力如下列图，由平衡条件可知，m 1g ＝F cot θ1，m 2g ＝F ′cot θ2因F ＝F ′，如此m 1m 2＝cot θ1cot θ2所以B 、C 两项正确．8．如下列图A 、B 是带有等量的同种电荷的两小球，它们的质量都是m ，它们的悬线长度是L ，悬线上端都固定在同一点O ，B 球悬线竖直且被固定，A 球在力的作用下，偏离B 球x 的地方静止平衡，此时A 受到绳的拉力为F T ；现保持其他条件不变，用改变A 球质量的方法，使A 球在距B 为x /2处平衡，如此A 受到绳的拉力为()A ．F TB ．2F TC ．4F TD ．8F T[答案]D[解析] 对A 球受力分析如下列图，F 斥和F T 的合力F 与mg 等大反向，由几何知识知，F 、F T 、F 斥组成的力的矢量三角形与几何△OAB 相似，所以：x k Q A Q B x2＝L F T 当A 、B 间距变为x 2时：x2k Q A Q B (x 2)2＝L F T ′ 解以上两式得F T ′＝8F T ，应当选D.二、非选择题9．如下列图，半径为R 的硬橡胶圆环，其上带有均匀分布的正电荷，单位长度上的电荷量为q .现在环上截去一小段长度为L (L ≪R )的圆弧AB ，如此在圆环中心O 处的电场强度的大小为________．[答案]kLq /R 2[解析] 未截去圆弧AB 时，整个圆环上的电荷分布关于圆心对称，如此O 处的电场强度为0.截去圆弧AB 后，除CD (和AB 关于O 对称的一小段圆弧)外，其余的电荷在O 处的场强为0，如此CD 在O 处的场强就等于中心O 处电场强度E .CD 上所带电荷量为Lq ，根据点电荷场强公式可得E ＝kLq /R 2.10．如下列图，真空中O 点有一点电荷，在它产生的电场中有a 、b 两点，a 点的场强大小为E a ，b 点的场强大小为E b ，E a 、E b 的方向如下列图，如此关于a 、b 两点场强大小的关系是________．[答案]E a ＝3E b[解析] 由题知：E a ＝k Q (ab sin30°)2＝4kQ (ab )2， E b ＝k Q(ab sin60°)2＝4kQ 3(ab )2， 所以有：E a ＝3E b .11．在绝缘水平面上固定着带电小球A ，其质量为M ，所带电量为Q .带电小球B 与A 之间相距为r ，质量为m ，所带电量为q .现将小球B 无初速释放，求：(1)刚释放小球B 的加速度为多大？(2)释放后B 做什么运动？[答案](1)k mr 2(2)见解析 [解析](1)由库仑定律与牛顿第二定律得F ＝k r 2＝ma ，a ＝k mr 2(2)由于小球B 逐渐远离小球A ，即r 变大，F 变小，a 变小，小球B 做加速度减小的加速运动．12．如下列图，绝缘水平面上静止着两个质量均为m ，电量均为＋Q 的物体A 和B (A 、B 均可视为质点)，它们间的距离为r ，与水平面间的动摩擦因数均为μ，求：(1)A 受的摩擦力为多大？(2)如果将A 的电量增至＋4Q ，两物体开始运动，当它们的加速度第一次为零时，A 、B 各运动了多远距离？ [答案](1)k Q 2r 2(2)各运动了Q k μmg －r 2[解析](1)由A 受力平衡，得：A 受的摩擦力为：F A ＝F 库＝k Q 2r2. (2)当加速度第一次为零时，库仑力和滑动摩擦力大小相等μmg ＝k 4Q 2r ′2，r ′＝2Q k μmg间距增大了2Q k μmg－r 因A 、B 的质量相等，所以加速度在这段时间内的任何时刻总是等大反向，因此A 、B 运动的距离相等，各运动了Qk μmg －r 2. 13．质量为m 的小球A 在绝缘细杆上，杆的倾角为α.小球A 带正电，电量为q .在杆上B 点处固定一个电量为Q 的正电荷，将小球A 由距B 点竖直高度为H 处无初速释放．小球A 下滑过程中电量不变．不计A 与细杆间的摩擦，整个装置处在真空中．静电力常量k 和重力加速度g .(1)A 球刚释放时的加速度是多大？(2)当A 球的动能最大时，求此时A 球与B 点的距离．[答案](1)g sin α－k sin 2αmH2 (2)k mg sin α[解析](1)根据牛顿第二定律mg sin α－F ＝ma .根据库仑定律F ＝kr 2，r ＝H /sin α.解得a ＝g sin α－k sin 2αmH 2. (2)当A 球受到合力为零、加速度为零时，动能最大．设此时A 球与B 点间的距离为R ，如此mg sin α＝k R 2，解得R ＝k mg sin α. 14．在一绝缘支架上，固定着一个带正电的小球A ，A 又通过一长为10cm 的绝缘细绳连着另一个带负电的小球B ，B 的质量为0.1kg ，电荷量为19×10－6C ，如下列图，将小球B 缓缓拉离竖直位置，当绳与竖直方向的夹角为60°时，将其由静止释放，小球B 将在竖直面内做圆周运动．释放瞬间绳刚好张紧，但无张力．g 取10m/s 2.求(1)小球A 的带电荷量；(2)小球B 运动到最低点时绳的拉力．[答案](1)5×10－6C(2)1.5N[解析](1)小球B 刚释放瞬间，因v ＝0故垂直切线方向mg cos60°＝kq A q B L 2 代入数值，求得q A ＝5×10－6C(2)因释放后小球B 做圆周运动，两球的相对距离不变，库仑力不做功，由机械能守恒得mg (L －L cos60°)＝12mv 2 由最低点F T ＋kq A q B L 2－mg ＝mv 2L由以上各式得：F T ＝32mg ＝1.5N。
