is there any reason why "waratteru ka naiteru noka" uses first the ka particle for the first part and no ka for the second?


Dragon Ball Super ending 9 <https://www.youtube.com/watch?v=5lRjWkjHKDg>

in a part of the song says

> "waratteru ka naiteru noka"

which is translated as

> were you laughing or were you crying?

Is there any reason why the first part uses the particle "ka" and the second
"no ka"? is there a rule or something for doing so in a case like this?




Please look at: [What is the meaning of のか and how does it differ from
か?](https://japanese.stackexchange.com/questions/18613/what-is-the-meaning-
of-%E3%81%AE%E3%81%8B-and-how-does-it-differ-from-%E3%81%8B)

Maybe by parsing, as @psosuna noted, it would sound more like, "Were you
laughing, or could you have been crying?"

On the other hand, it could just be added syllables to make the song lyrics
fit.
