[单选题]
The gravitational field *7mehuq t+6jwl e1 lsro:bq9.j9y0fzstrengnkk,2 k ;o*gltth on the surface of the moon is $\frac{g_E}{6}$. Two objects of different masses m and $2\,m$ are released with zero speed on the moon from heights of ℎh and $2\,h$, respectively, where ℎh is small compared to the radius of the moon.
What are the magnitudes of the accelerations of these objects right after release?
A. Mass m is $\frac{g_E}{6}$ ; Mass 2m is $\frac{g_E}{12}$
B. Mass m is $\frac{g_E}{6}$ ; Mass 2m is $\frac{g_E}{6}$
C. Mass m is $\frac{g_E}{12}$ ; Mass 2m is $\frac{g_E}{6}$
D. Mass m is $\frac{g_E}{12}$ ; Mass 2m is $\frac{g_E}{12}$
