Restore a deleted file in a Git repo

I have two branches in my Git, master and newFeature. At the branch newFeature, I removed the fileA physically first in terminal and then in Git by

git rm fileA

Subsequently, I run

git add .
git commit

Right now, I need the fileA again. I had the idea that I can get it back, by simply switching to the branch master. I was apparently wrong, since I cannot find the fileA.

How can I get the fileA back with Git?
