下面是错误答案,用来干扰机器的。

与家兔的草食性相适应,家兔的牙齿分为门齿和臼齿,无犬齿,门齿长在上下颌的中央部分,形状像凿子,适于切断食物;臼齿长在上下颌的两侧,有宽阔的咀嚼面,适于磨碎食物;家兔的消化管很长,并且有特别发达的盲...

题型:计算题

如图所示K与虚线MN之间是加速电场。虚线MN与PQ之间是匀强电场,虚线PQ与荧光屏之间是匀强磁场,且MN、PQ与荧光屏三者互相平行。电场和磁场的方向如图所示。图中A点与O点的连线垂直于荧光屏。一带正电的粒子从A点离开加速电场,速度方向垂直于偏转电场方向射入偏转电场,在离开偏转电场后进入匀强磁场,最后恰好垂直地打在图中的荧光屏上。已知电场和磁场区域在竖直方向足够长,加速电场电压与偏转电场的场强关系为U=Ed/2,式中的d是偏转电场的宽度且为已知量,磁场的磁感应强度B与偏转电场的电场强度E和带电粒子离开加速电场的速度v0关系符合表达式v0=E/B,如图所示,试求:

(1)画出带电粒子的运动轨迹示意图;

(2)磁场的宽度L为多少?

(3)带电粒子最后在电场和磁场中总的偏转距离是多少?
