Its total energy in the orbit is (Mass of the earth = \[6.0\times {{10}^{24}}kg\]  and\[~\text{G }=\text{ 6}.\text{67 }\times \text{1}{{0}^{-\text{11}}}\text{ N}-{{m}^{2}}\text{/k}{{\text{g}}^{\text{2}}})\]

A) \[\text{6}.\text{6 }\times \text{ 1}{{0}^{9}}\text{ joule}\] 

B)         \[-\text{ 6}.\text{6 }\times \text{ 1}{{0}^{\text{9}}}\text{ joule}\]  

C) \[\text{6}.\text{6 }\times \text{ 1}{{0}^{-\text{9}}}\text{ joule}\]

D)        \[-\text{ 6}.\text{6 }\times \text{ 1}{{0}^{-\text{9}}}\text{ joule}\]
