But you can also look at it qualitatively, so, if you think about the force between the electron and the proton, you could just qualitatively think about what's happening.

但你也可以定性的来研究这个问题，所以如果你们考虑电子,和质子之间的作用力,你可以定性的来想。

So, I know this is a simple example and I can see everyone pretty much got it right, and probably those that didn't actually made some sort of clicker error is my guess.

分别是质子和电子,我知道这是个很简单的问题，你们大部分人都做对了,我猜那些没做对的大概是因为点错了。

The electron is just a little gnat in comparison to the proton.

电子十分的渺小,在和质子相比起来。

And, as I mentioned, we left off and as we started back here to describe the atom and how the atom holds together the nucleus and the electron using classical mechanics.

我之前提及过，我们上次,讲到应用经典力学如何描述,一个原子以及原子如何把质子,和电子束缚在一起，今天我们要。

So, we just talked about the force law to describe the interaction between a proton and an electron. You told me that when the distance went to infinity, the force went to zero. What happens instead when the distance goes to zero? What happens to the force?

我们刚刚讨论了描述质子,和电子之间相互作用力的定律,当距离变为无穷时,力变为零，那当距离变为,零时会发生什么？,这时候力是多少？
