question
particles particle-の particle-か
when no ka question mark is used instead of ka?
In conversation especially this is important and really depends on who one is
speaking to and how formal your speech is.

For example if asking someone where they went...

Asking someone of authority (using keigo) どこにいきになりましたか？one would use か at the
end.  
Asking someone you are mildly acquainted with どこにいきましたか? か would still be
present  
Asking your best friend you've known all your life どこにいった/どこにいったの？you don't
have to use か here or you could also end with の.

When writing sentences, as not to cause confusion, please use か to make it
obvious to the reader that a question has been asked, unless it has been made
blatantly clear that casual speech is being used.
