initial U = -GMm/r
=> later
=> r becomes 2r and m becomes 3m
=> so final U = -GM(3m)/(2r) = -3GM/2r
=>hence ratio is 2:3

But the answer is 6:1
i have taken it with respect to the object being on the surface of earth initially you can consider any height H and solve it the same way
I am not able to solve it ....
Please solve it....
