The drawing shows a wire tooth brace used by orthodontists. The topmost tooth is protruding slightly, and the tension in the wire exerts two forces Tand T.
on this tooth in order to bring it back into alignment. If the forces
have the same magnitude of 22.0 N, what is the magnitude of the net force exerted on the tooth by these forces?
