So physics is not part of the homework? (<--"homework" is one word)
She thought I was spending time on physics, but I was doing my homework.
It would be repetitive to use "spending time on" twice. You could say either "my homework" or leave out "my" because you wouldn't be doing anyone else's homework.

They're all fine. While "on" is not needed with "doing". it isn't wrong.
