(20分)在考古中为了测定古物的年代,可通过测定古物中碳14与碳12的比例,其物理过程可简化为如图所示.碳14与碳12经电离后的原子核带电量都为q,由静止经电压U加速后从O点进人磁感应强度为B的匀强磁场,OM为磁场的下边界线,可在OM上适当位置放置粒子记数器,从而测定碳14与碳12的比例(不计粒子的重力及粒子间的相互作用力).求:

(1)碳14与碳12在磁场中运动的半径比

(2) 在实际中并不是所有粒子都垂直于OM沿ON射入磁场,而是分布在与ON成一定夹角θ的纸面内,要使两种粒子运动到OM直线上时能区分在不同区域,θ角的范围;

(3) θ取最大时,用阴影表示出碳14粒子在磁场中可能出现的区域.
