     If total energy of satellite is E, what is its potential energy?

    A)  \[2E\]            

    B)  \[-2E\]

    C)  \[E\]               

    D)  \[-E\]

    Correct Answer: A

    Solution :

     Potential energy of satellite \[U=-\frac{GMm}{r}\] and total energy of satellite \[E=-\frac{GMm}{2r}\] Therefore, \[U=2\,E\]
