1.Use the Heisenberg uncertainty principle to calculate Deltax for an electron with Deltav = 0.585 m/s.
2.By what factor is the uncertainty of the (above) electron's position larger than the diameter of the hydrogen atom?
(Assume the diameter of the hydrogen atom is 1.00×10-8 cm.)
3.Use the Heisenberg uncertainty principle to calculate Deltax for a ball (mass = 178 g,diameter = 8.40 cm) with Deltav = 0.585 m/s.
4.The uncertainty of the (above) ball's position is equal to what factor times the diameter of the ball?

1.Δx＞h/2πmΔv=6.26*10^-34/2*3.14*9.1*10-31*0.585=1.87*10^-4m=1.87*10^-2cm
2.电子x坐标不确定范围与氢原子的直径之比为:Δx/10^-8=1.87*10^6
3.Δx＞h/2πmΔv=6.26*10^-34/2*3.14*178*10^-3*0.585=9.56*10^-32cm
4.小球的x坐标不确定范围与其直径之比为:Δx/8.4=9.56*10^-32/8.4=1.14*10^-32
