Answer 2

Friction

Explanation:

Friction always opposes relative motion between the surfaces in contact with each other. The force of friction between the eraser and paper brings about wear and tear of the eraser and it turns into minor pieces. This friction the eraser and the paper rubs off some rubber particles from the eraser. Thus, the eraser loses tiny pieces of rubber due to friction.
