Answer:
The simplified expression is [tex]M = \frac{v^2 r}{G}[/tex]
Explanation:
From the question we are told that
[tex]M = \frac{ \frac{m v^2}{r} }{\frac{ mG}{r^2 } }[/tex]
So simplifying we have
[tex]M = \frac{m v^2}{r} * \frac{r^2 }{ mG }[/tex]
[tex]M = \frac{v^2 r}{G}[/tex]
Thus the simplified formula is [tex]M = \frac{v^2 r}{G}[/tex]
