8.近期,中国载人探月工程登月任务已启动实施,计划在2030年前实现中国人首次登月。已知月球的半径为R,万有引力常量为G,假设宇航员在距离月球表面高处(h远小于R),以初速度v0,竖直向上抛出一小球,小球经时间t落到月球表面,在月球的上空,保障卫星正在绕月球做周期为工的匀速圆周运动,忽略月球自转。则下列说法正确的是(.));A.月球表面的重力加速度为2(v0t+h)t^2B.月球的质量为为2(v0t+h)RGt^2c.月球的第一宇宙速度为2(v0t+h)RtD.保障卫星的高度为T^2R^2(v0e+h)2^2t-R

14.(13分)在竖直平面内建立如图所示的直角坐标系xOy,,第一、二象限内有水平向左、大小相等的匀强电场,第三、四象限内有磁感应强度大小为B、方向垂直于坐标平面向里的匀强磁场,在y轴的某个适当的位置放置有水平绝缘光滑的小支架,支架上静止放置一质量为m、不带电的金属小球a,另一与小球a一样大、质量为13m.、带电荷量为q的金属小球b从x轴的某点,垂直于x轴以速度v0,竖直向上射入第一象限,运动一段时间后以速度v0,沿x轴负方向与小球a发生弹性碰撞且电荷量发生转移,过了一段时间小球a从x轴上的某点进入第三象限,不计两球间的库仑力及空气阻力,重力加速度大小为(1)求小球a从x轴上某点进入磁场时的该点的位置坐标。(2)若B=3mgqv0,求小球a第一次在磁场中运动离x轴的最远距离和最大速度,

8.某探究小组通过资料获得如下信息:距离火星表面高度为火星半径的卫星绕其做圆周运动的周期为T1,火星自转的周期为Tz,火星两极处的重力加速度为80。火星赤道处静止一质量为m的探测器,则火星给其的支持力大小为A.(8Tz^2-T1^2)mg08T2^2B.(T2^2-8T1^2)mg08T2^2C.(8Tz^2-Tj)mg08T9^2D.(T2^2-8T1^2)mg08T1^2
