Problem

Which of the following expressions correctly relates the orbital period

T

of a small satellite to its orbital radius

R

around a planet of mass

M

(where

G

is the universal gravitational constant)? a)

T^{2}=\dfrac{GM}{4\pi^{2}}R^{3}

T^{2}=\dfrac{4\pi^{2}}{GM}R^{3}

T^{2}=\dfrac{4\pi^{2}}{GM}R

T^{2}=\dfrac{4\pi^{2}}{GM}R^{2}
