c:proportional 1/r^2

c:proportional 1/r^2

d:(m1+m2)g

d:(m1+m2)g

d:(m1+m2)G

d:(m1+m2)G

equation is U=-Gm1*m2/r

equation is U=-Gm1*m2/r

Problem is is that I want to choose B as my answer but A also

sounds correct. Which one is right?

Answer is C ….

equation is U=Gm1m2/r^2 hence it is proportional to 1/r^2. Hence

option:c
