There is a limit beyond which further polishing of a surface increases rather than decreases frictional force. Explain.

1.	There is a limit beyond which further polishing of a surface increases rather than decreases frictional force. Explain.
Answer» Solution :When the SURFACE is POLISHED beyond certain limit the actual area of contact increases. This increases the force of attraction between the molecules and HENCE friction ALSO increases.
