And so, you know from your Newtonian mechanics, as you were learning in 8.01, the dynamic force here mv^2/r is mv squared over r.
在8。01节对牛顿动力学系统的学习中,我们可以知道这里的运动受力,就是。
And we plug in our values and end up with mv squared mv^2/r-Ze^2/ over r minus Ze squared over And I am going to call this equation two.
我们最后的结果,就是,我把这称为方程式二。
r=nh/mv That will give us 2 pi r goes as nh over mv.
2π
/2mv^2 We know that we have one-half mv squared.
我们现在已经有了一个。
/2mv^2 So it is simply one-half mv squared.
它只是。
This is going to have one-half mv squared where this is the mass of the electron.
有了电子的质量,就可以用1/2mv^2算出其动能。
