Question

It is known that, the minimum velocity required by a spaceship to leave planet X is four times that needed to leave planet Y. Given that both planets X and Y have the same mass, calculate the ratio of the radius of planet X to that of planet Y (r_x / r_y).

Accepted Answer

$\frac{r_{x}}{r_{y}}=\frac{1}{16}$

Answer

$\frac{r_{x}}{r_{y}}=\frac{1}{16}$

Answer

$\frac{r_{x}}{r_{y}}=\frac{1}{16}$

Answer

$\frac{r_{x}}{r_{y}}=\frac{1}{16}$

It is known that, the minimum velocity required by a spaceship to leave planet X is four times that needed to leave planet Y. Given that both planets X and Y have the same mass, calculate the ratio of the radius of planet X to that of planet Y (rx / ry).
