14.(13分)如图所示,电场强度大小为E=3mg4q、方向水平向左的匀强电场充满整个空间,电场中有一个与水平方向成=53^的光滑斜面与一个光滑的半径R=1m的竖直圆轨道在A点相切,B点为圆轨道的最低点,C点为圆轨道的最高点。一质量为m=1kg,,电荷量为-q(q>0)的带电小球从斜面上静止释放,已知重力加速度大小g=10m/s^2,53^=0.8,53^=0.6,,若小球能通过C点,则其会被其它装置取走。(1)若运动过程中小球对轨道的最大压力大小为67.5N,,求小球释放点与A的距离;(2)若将电场方向反向,场强大小不变,小球恰能到达C点,求小球运动在过程中对轨道的最大压力大小。

21.某同学购买了一款户外分体式燃气炉,准备去户外野炊。用该燃气炉烧水时,把初温为20^C的1kg的水加热到100^C,燃烧了0.025m^3天然气。水的比热容c7k=4.210^3J/(kg^C),天然气的热值取410^7J/m^3。求:(1)水吸收的热量;(2)燃气炉烧水的效率。

3.如图所示,司机为方便卸货,在车厢尾部与地面之间搭建了一个斜面。其中车厢尾部到地面的高度为1.2m,车厢尾部到地面间的木板长度为2m。若货物恰好能沿木板匀速下滑,则货物与木板间的动摩擦因数为()A.0.75B.0.8C.0.6D.0.5
