Question

What happens to the force of friction if the surface of contact is polished?​

Answer 1

$\mathcal\red{Answer}$

⟹When two surfaces in contact are polished beyond a certain limit and made extremely smooth, they come in intimate contact with each other.

⟹Now, the force of adhesion comes into play. Due to this force, the motion of one surface over another surface becomes retarding and hence causes an increase in the friction.

Answer 2

Answer:

friction on the surface reduces

Explanation:

friction can never be 0
