15.(15分)如图所示,竖直面内有一固定轨道ABC,AB与BC相切于B点,小滑块与AB段的动摩擦因数为u=23,BC段是半径为R=m的光滑圆弧,BC连线水平。轨道所在处有垂直纸面向外的匀强磁场,磁感应强度大小B=2T。,将一个质量为m=1kg、带电量为+q=1C的绝缘小滑块自图中P点以水平速度v0=3m/s向右抛出,刚好可以无碰撞地进入斜面,已知斜面倾角=53^,,小滑块在进入BC轨道前已匀速运动,重力加速度g取10m/s^2,53^=0.8。求:(1)P与A之间的水平距离;(2)小滑块在C点时的速度大小vC;(3)小滑块在轨道最低点D时对轨道的压力。

8.如图所示,平行板电容器与电动势为E的直流电源(内阻不计)连接,下极板接地,静电计所带电荷量很少,可被忽略。一带负电油滴被固定于电容器中的P点。现将平行板电容器的下极板竖直向下移动一小段距离,则A.平行板电容器的电容将变大B.静电计指针张角变小C.带电油滴的电势能将减少D.若先将上极板与电源正极的导线断开,再将下极板向下移动一小段距离,则带电油滴所受电场力不变
