Another wierd question.

The following formula may be used to study planetary motion.

GmM/R^2=m4pi^2R/T^2. (Hope its not too confusing)

Make T the subject of the equation.

Thanks eveyone for the help.

$\displaystyle \frac{GmM}{R^2}=\frac{m4\pi^2R}{T^2}$

$\displaystyle T^2=\frac{m4\pi^2R^3}{GmM}$

$\displaystyle T=\sqrt{\frac{m4\pi^2R^3}{GmM}}$

$\displaystyle T=2\pi\sqrt{\frac{mR^3}{GM}}$
