The gravitational field strbdy;y pmvg.g 86z r1:z(i+uxde .r cnd(6mwfgy5,yk9 pngth 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 $\frac{g_E}{12}$
