Question 9

A planet of radius $R\,$ has an acceleration due to gravity at its surface of $g$ . A spacecraft of mass $m\,$ is in a stable circular orbit around the planet at an altitude where the local gravitational field strength is $g9\displaystyle \frac{g}{9}$ .

What is the orbital speed of the spacecraft?

$13gR\frac{1}{3}\sqrt{gR}$

$12gR\frac{1}{2}\sqrt{gR}$

$gR3\sqrt{\frac{gR}{3}}$

$2gR3\sqrt{\frac{2gR}{3}}$
