And you will form a crystal of sodium chloride as a result of this need to form crystal expressed through the Coulomb's Law.

你能得到氯化钠晶体,因此，形成晶体所需要的条件,在库伦定律中通篇都有表达。

So, if we think about the force that occurs between a positively and a negatively charged particle, what we have is essentially a Coulomb force, so we can describe this as a force of attraction.

一个带负电的粒子之间，的作用力,这本质上就是库伦力，我们可以把它，描述成一个引力。

0 And it has a mass of 9.11 times 10 to the minus 31 kilograms The charge compensation comes out of the nucleus with the proton and it is positive 1.6 times 10 to the minus 19 coulombs.

它的质量是9。11乘以0,到负31千克,电荷补偿来自于,有质子的原子核,它是+1。6*10^库伦。

Essentially for our purposes here, you can just think of it as a conversion factor.

就是去掉库伦标签，这就是我们。

PROFESSOR: And this is a question based on where we left off on Wednesday -- we were talking about Coulomb's force law to describe the interaction between two particles and good job, most of you got this correct.

教授：这是我们上次最后,留下的问题-我们讲到,描述粒子间相互作用的,库伦定律，很好,大部分人都做对了。

We can use the Coulomb force law to explain this where we can describe the force as a function of r.

我们用库伦定律解释它,力作为距离r的函数,让我们考虑一下。

So, just, if you can take what I'm saying for a moment right now that in fact this should collapse in this very small time frame, we have to see that there's a problem with one of these two things, either the Coulomb force law or Newtonian mechanics. So, what do you guys think is probably the issue here?

所以如果你们考虑我,开始说的这个塌缩应该,发生在很短的时间里，那么这两者之一就有问题,要么是库伦定律,要么是牛顿力学,你们觉得应该是哪个的问题？

In addition to that, we have that epsilon nought value, remember that's the permittivity constant in a vacuum, and basically that is what we use as a conversion factor to get from units. We don't want namely coulombs to units, we want that will allow us to cancel out in this equation.

这是电子的电荷，此外，我们有epsilon零，记住这是真空的介电常数，这是我们用来转换单位的转换常数,我们不想用库伦单位，我们希望这个可以在方程中约去它。
