10.如图所示,一倾角为=30^的光滑斜面固定在水平面上,斜面的底端固定一垂直斜面的挡板,上端固定一定滑轮0。劲度系数为k=8mg3d的轻弹簧下端固定在挡板上,上端与质量为2m的物块Q连接。一跨过定滑轮O的轻绳一端与物块Q连接,另一端与套在水平固定的光滑直杆上质量为m的物块P连接。初始时物块P在水平外力F作用下静止在直杆的A点,且恰好与直杆没有相互作用,轻绳与水平直杆的夹角也为。去掉水平外力F,物块P由静止运动到B点时轻绳与直杆间的夹角=53^。,已知滑轮到水平直杆的垂直距离为d,重力加速度大小为g,弹簧轴线、物块Q与定滑轮之间的轻绳与斜面平行,不计滑轮大小及摩擦,53^=0.8,53^=0.6。。则下列说法正确的是A.物块P在A点时外力F的大小为0.75mgB.物块P从A点运动到B点时,物块Q沿斜面下移的距离为3d4C.物块P在A点和B点,这两个状态弹簧弹性势能相等D.物块P运动到B点时,物块P、Q的速度之比为3:5
