This question is now closed as offtopic on 2 reasons:
- It is mainly math, although its markup and formulation clearly shows the described problem is a physical problem. The current review practice is that also this type of questions are closed as offtopic and sometimes migrated to the MathSE.
- It is considered as a homework question (not by me, but it is a different topic).
Now the problem is that if you vote to close this question as homework, it won't be migrated to the MathSE, it will be simply closed. This is what happened. As I voted this question (to migrate to MathSE), it had already 2 close votes as homework and 2 close votes to migration.
My vote to migrate resulted that the question was closed as homework. The criteria to fulfill to migrate a question is hard(*), but there is no reason to not try to fulfill it, if the question is okay.
If the question had been migrated to the MathSE, it could have been received very well there.
I find it a little bit dishonest, because I hadn't ever voted this to close on the homework close reason, despite that the close reason shows as if it had been also my decision. I voted to migrate it to the MathSE, where it would be ontopic.
In this, and similar cases, if you think a question should be closed on multiple reasons, and at least one of them is migration, please vote for migration.
(*) From the 5 close votes, at least 3 or 4 should vote to migrate, and to the same site. If this requirement is not passed, the question is simply closed.
