(3)在弹簧的弹性限度内,在秤盘中轻轻放入被测物体,待秤盘静止平衡后,导体杆右端点P正好处于直电阻丝R0下端b处,要使此时电压表达到满偏,则滑动变阻器R接人电路的阻值为aa已知弹簧的劲度系数k=9.810^3N/m,,当地重力加速度g=9.8m/s^2,,则被测物体的质量m=kg。若在电压表的刻度盘上标示相应的质量数值,即将该电压表改装成测量物体质量的仪器,则质量刻度是(填“均匀”或“非均匀”)的。

14.(13分)如图甲所示,水平正对放置的金属板A和B的距离为d,它们的右端放着垂直于金属板的靶MN,,现在A、B板间加上如图乙所示的电压,电压的正向值为U0(A板电势高于B板电势),反向电压值为U02,且每隔T2变向1次。现将质量为m、电荷量为+q的粒子束从A、B左侧的中点O以平行于金属板的方向射人两板之间,设粒子能全部打在靶上且所有粒子在A、B间的飞行时间均为T0,不考虑重力的影响。(1)试定性分析在t=0时刻从O点进入的粒子,时间内在垂直于金属板方向上的运动情况。(2)在距靶MN的中心'点多远的范围内有粒子击中?(3)要使粒子能全部打在靶MN上,电压,的数值应满足什么条件?(写出U0、m、d、q、T的关系式即可)
