14.(12分)受控热核聚变反应的装置中温度极高,因而带电粒子没有通常意义上的容器可装,而是由磁场将带电粒子的运动束缚在某个区域内。现有一个环形区域,其截面内圆半径R1=33m,外圆半径R2=1.0m,区域内有垂直纸面向外的匀强磁场(如图所示),已知磁感应强度B=1.0T,被束缚的带正电粒子比荷为qm=4.010^7C/kg,,不计带电粒子的重力和它们之间的相互作用,结果均保留到小数点后两位,(1)若中空区域中的带电粒子由点沿环的半径方向射入磁场,求带电粒子不能穿越磁场外边界时的最大速度v0;(2)若中空区域中的带电粒子以(1)中的最大速度v0沿圆环半径方向射人磁场,求带电粒子从刚进入磁场某点开始到第一次回到该点所需要的时间。

9.小孩特别喜欢的一种玩具电陀螺如图甲所示,陀螺可在圆轨道外侧旋转而不脱落,好像轨道对它施加了“魔法”一样,被称为“魔力陀螺”。它可等效为一质点在圆轨道外侧运动的模型,如图乙所示,在竖直平面内固定的强磁性圆轨道半径为R,A、B两点分别为轨道的最高点与最低点,陀螺沿轨道外侧做完整的圆周运动,受到圆轨道的强磁性引力始终指向圆心,且大小恒为陀螺所受重力的8倍,已知陀螺的质量为m,重力加速度大小为g,不计摩擦阻力,则下m,列关于陀螺运动的说法正确的是g,A.小孩玩陀螺过程中陀螺做匀速圆周运动B.要使陀螺做完整的圆周运动,则陀螺在A点的速度不能超过3gRC.若陀螺能做完整的圆周运动,则陀螺对A、B两点的压力差恒为6mgD.若陀螺恰好做完整的圆周运动,则其运动到A点时对轨道的压力为零
