How can i mathematically prove the following equation:(adsbygoogle = window.adsbygoogle || []).push({});

I have to prove that the minimum speed required to maintain orbit around the Earth is (given the mass of the earth and universal gravitation constant)

v = 2.00x10^7

(root)r

I have to basically prove this equation:

v = GmE

r

P.S. the whole equation to the above is square rooted, and the r should be UNDER GmE).
