And so that means that the frictional force is a maximum value possible, N which is the static friction coefficient times N, and therefore that is mu of s mgcos And when will that happen?

这意味着,摩擦力在最大值，静摩擦力因数乘以,等于mus乘以,θ，times，mg，times，the，cosine，of，theta。,什么时候会发生？

So that means that N of P must be in magnitude the same as the frictional force.

这意味着PN必须,在大小上,与摩擦力相同。

If you look at the ground state in two different systems -If you look at the ground state which is n equals one, think about this, if I increase the proton charge, the Coulombic force of attraction is greater.

如果你观察两个不同系统的基态,当你观察n，等于1的基态时，试想一下，如果我增加质子电荷，相互吸引的库仑力就会更大。
