The mass of the Earth is M_E and the mass of the Moon is M_M. Their respective radii are R_E and R_M.

Which is the ratio \(\frac{{{\text{escape speed from the Earth}}}}{{{\text{escape speed from the Moon}}}}\)?

A.     \(\sqrt {\frac{{{M_{\text{M}}}{R_{\text{M}}}}}{{{M_{\text{E}}}{R_{\text{E}}}}}} \)

B.     \(\sqrt {\frac{{{M_{\text{E}}}{R_{\text{E}}}}}{{{M_{\text{M}}}{R_{\text{M}}}}}} \)

C.     \(\sqrt {\frac{{{M_{\text{E}}}{R_{\text{M}}}}}{{{M_{\text{M}}}{R_{\text{E}}}}}} \)

D.     \(\sqrt {\frac{{{M_{\text{M}}}{R_{\text{E}}}}}{{{M_{\text{E}}}{R_{\text{M}}}}}} \)

C
