An artificial satellite of mass 200 kg revolves around the earth in an orbit of average radius 667 km. 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.        \[-\text{ 6}.\text{6 }\times \text{ 1}{{0}^{-\text{9}}}\text{ joule}\]
