[单选题]
A satellite of mass 4:itr*i t/x*yuu wn 3y70 o+bit6rv+o j8kg is moved from one point in space to another for experimental purposes. The 8ob+iv+ to jr6graph below shows how the gravitational potential V of the points that the satellite moves through varies with time t.


The change in gravitational potential energy of the satellite is 600 MJ. Which of the following gives the magnitude of the gravitational potential $V_f$​ at the final location of the satellite?

A. $-20\,MJ\,kg^{-1}$
B. $-15\,MJ\,kg^{-1}$
C. $-10\,MJ\,kg^{-1}$
D. $-5\,MJ\,kg^{-1}$


参考答案:  B
