When two surfaces are polished, the friction coefficient between them increases. but the friction coefficient increases and becomes very large if the surfaces are made highly smooth. plz explain

When two surfaces are polished, they are made smooth, hence less fricition and friction coefficient.
Because smoothening removes the very small irregularies in the surface, thereby decreasing friction and friction coefficient.
