A) 2
B) \[\frac{1}{2}\]
C) \[\frac{1}{\sqrt{2}}\]
D) \[\sqrt{2}\]
Correct Answer: B
Solution :
Key Idea: The potential energy of satellite is twice its kinetic energy but opposite in sign. |
Potential energy, |
or |
Kinetic energy, |
Thus, |
Note: The total energy . This energy is constant and negative, i.e., the |
system is closed. The farther the satellite from the earth the greater its total energy. |
