33.(14分)如图,一质量不计,可上下自由一点的活塞将圆筒分为上下两室,两室中分别封闭有理想气体,筒的侧壁为绝缘体,上底N,下底M及活塞D均为导体并按图连接,活塞面积。在电键K断开时,两室中气体压强均为,ND间距,DM间距,将变阻器的滑片P滑到左端B,闭合电键后,活塞D与下底M分别带有等量异种电荷,并各自产生匀强电场,在电场力作用下活塞D发生移动。稳定后,ND间距,DM间距,活塞D所带电流的绝对值(式中E为D与M所带电荷产生的合场强,常量)求:

(1)    两室中气体的压强(设活塞移动前后气体温度保持不变);

(2)    活塞受到的电场力大小F;

(3)    M所带电荷产生的场强大小和电源电压U;

(4)    使滑片P缓慢地由B向A滑动,活塞如何运动,并说明理由。

[解析](1),解得

(2),解得

根据活塞受力的平衡,。

(3)因为E为D与M所带电荷产生的合场强,是M所带电荷产生的场强大小,所以E=2,所以,所以=,得。

电源电压.

(4)因减小,减小,向下的力减小,增大,减小,向上的力增大,活塞向上移动。

本题考查电场、电场力,气体等综合知识和分析综合能力。

难度:难。

把电场和气体结合一起,具有新意。

解析者言:因为没有见到官方答案,加之时间紧,水平限,可能有不妥甚至错误,如有答案,请纠正。

高考物理,大多以理综形式呈现,物理单科卷,主要为江苏省卷、上海卷、广东卷,我多年研究,认为3卷呈三国鼎立之势。我的感觉:江苏省卷难,上海卷巧,广东卷平。上海人就是聪明:题目多,有容易的,容易的多,也有难的,难的少。不像江苏省卷,总题量太少,难题多。
