2014 F = ma Exam — Question 22

22. A body of mass M and a body of mass m ≪M are in circular orbits about their center of mass under the inﬂuence of their mutual gravitational attraction to each other. The distance between the bodies is R, which is much larger than the size of either body. A small amount of matter δm ≪m is removed from the body of mass m and transferred to the body of mass M. The transfer is done in such a way so that the orbits of the two bodies remain circular, and remain separated by a distance R. Which of the following statements is correct? — Source: Question 22, 2014 F = ma Exam, © 2014 American Association of Physics Teachers (AAPT) and the U.S. Physics Team.
