It is practically impossible to teach good programming style to students that have had prior exposure to Basic; as potential programmers they are mentally mutilated beyond hope of regeneration.

if someone gets the right answer, will you post the equation you used? Haven't really done this yet... just basic single object friction movement.
Well, guys you have got wrong answers.

Relative motion? Relative to what? If relative to the surface, then there is no minimum (0 is the lower bound).

By relative motion in blocks i mean there is different acceleration in all three blocks, so relative to each other.
We ain't and can't consider all three blocks as one, as we do in several problems where force is applied at the lowermost block.

If relative to each other, then 2.4 kg * g, or about 23.5 newtons on Earth.

Wait, you want all the blocks to be moving differently so that _no_ two can be the same?

If so, then how about 12/7*1.5 kg * g, i.e. 25.2 N.

Well, you are right, all blocks must have different acceleration. But yes, I want minimum force. So when that force is applied then the acceleration of blocks will be somehow similer, I mean tend to be equal.
So just draw FBD's of all three blocks, get the acceleration, put your concept of static and kinetic friction.
