1.一个电子电荷e=-1.6*10^-19C 验电器上移走的电子数=Q/e=7.5*10^-11/1.6*10^-19=46875*10^4
2.物体所带电荷等于多余或缺少电子的总电量
(1)多余电子带电荷Q=(-1.6*10^-19)6.25*10^19=-1.6*6.25C=-10C
(2)缺少电子带电荷Q=(1.6*10^-19)*10^8=1.6*10^-11C
2.物体所带电荷等于多余或缺少电子的总电量
(1)多余电子带电荷Q=(-1.6*10^-19)6.25*10^19=-1.6*6.25C=-10C
(2)缺少电子带电荷Q=(1.6*10^-19)*10^8=1.6*10^-11C
