Where should a back button be placed?

Right: back button above the form (good). Some forms or questionnaires appear across multiple pages and some people want to go back to check or change their answers. Unfortunately some users don't trust the browser back button because of their experiences of poorly designed forms that lose data when they click back.

Where should back button be on app?

Since the top left is pretty standard for most apps, this makes it recognizable for the user and therefore easier to find and use. This position is only difficult to reach for mobile devices. That is why the bottom left would also be possible, but the most important option like a next button is at the bottom.

Should I put a back button on my website?
