Show that the escape speed from a planet is related to the speed of a circulat orbit just above the surface of the planet by Ve = square root(2Vc), where Vc is the speed of an object in the circular orbit.(adsbygoogle = window.adsbygoogle || []).push({});

I'm looking at GMem(object)/r^2 = m(o)v^2/r

But I do not know if this equation will help or how to connect it together with anything else. Any help would be great.
