15.(20分)如图所示的坐标系中,半径为R的圆内存在沿x轴负方向的匀强电场以及正交的匀强磁场(图中电场、磁场均未画出),圆的圆心与坐标系的原点O重合,电场强度大小为E.图中的平行金属板与x轴平行,一重力可忽略不计的正电荷由下板的S静止释放,经电场加速后刚好由原点的小孔以沿y轴方向的速度射入圆形区域,电荷沿直线运动经时间t0离开半圆区域.求:(1)磁感应强度的大小以及磁场方向;(2)若仅撤走磁场,电荷经时间离开半圆区域,求粒子的比荷qm以及平行板间的电压;(3)将平行板间的电压增加到原来的16倍,同时撤走半圆区域的电场,电荷在半圆区域运动的时间.

5.“福建舰”是中国完全自主设计建造的首艘弹射型航空母舰,采用平直通长飞行甲板,配置电磁弹射和阻拦装置,满载排水量8万余吨。某舰载飞机在“福建规”上起飞前,先采用电磁弹射,舰载飞机由静止开始匀加速直线运动位移x1后,再靠常规动力匀加速直线运动位移x2后起飞。若该舰载飞机的起飞速度大小是电磁弹射过程刚结束时速度大小的k倍,则它靠电磁弹射加速过程中的加速度大小与它靠常规动力加速过程中的加速度大小的比值为D.(k^2-1)x2x1A.x2(k^2-1)x1B.x2k^2x1C.x1(k^2-1)x2
