[单选题]
The gravitational field streng g;t n;lrcszgsf: 2ue 41n4kq:th opt1dh qrq )gayj2roe u 8+*8gf-a+ )uon 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 $\frac{g_E}{12}$
