You always lose your m, and so you find that the speed at which it reaches the neutron star M R M neutron star times G divided by R neutron star.

你们发现，它到达中子星的速度,等于二次根号,乘以G，is，the，square，root，of，two,除以中子星的半径,你们应记住这等式。

But now notice, I can substitute now for this v squared, I can substitute the square of this that is the orbital speed and then I get M G over R.

现在注意我能,代替这个v平方，我能代入这个平方,那是轨道速度,然后得到MG在R上。
