A) \[\sqrt{\frac{2G{{M}_{e}}h}{{{R}_{e}}({{R}_{e}}+h)}}\]
B) \[\sqrt{\frac{2G{{M}_{e}}}{{{R}_{e}}+h}}\]
C) \[\sqrt{\frac{G{{M}_{e}}}{({{R}_{e}}+{{h}^{3}})}}\]
D) \[\sqrt{\frac{G{{M}_{e}}}{2({{R}_{e}}+h)}}\]
Correct Answer: C
Solution :
[c] \[V=\sqrt{\frac{G{{M}_{e}}}{{{R}_{e}}+h}}\]\[\Rightarrow \]\[W({{R}_{e}}+h)=\sqrt{\frac{G{{M}_{e}}}{({{R}_{e}}+h)}}\] \[\Rightarrow \]\[W=\sqrt{\frac{G{{M}_{e}}}{{{({{R}_{e}}+h)}^{3}}}}\]You need to login to perform this action.
