Answer 7

I think it can be done this way:

Imagine you are one of the spheres. You have to turn the other 2.
Suppose you are sphere:

1. Turn 2 and 3 at distances d and 3d.
2. Turn 1 and 3 at distances d and 2d.
3. Turn 1 and 2 at distances 3d and 2d.

From most difficult (= highest inertia) to most easy: 3, 1, 2.
