Solution

The correct option is C
It decreases friction

Irregularities on both the surfaces lock into each other. The force applied would depend on the number of these irregularities and hence friction decreases when irregularities decrease.

What impact would decreasing irregularities on two surfaces rubbing each other have on the frictional force between them?

Consider the following statements:

Statement 1: Rough surfaces generally have more friction between them.
Statement 2: When we attempt to slide one surface over another, we have to apply a force to overcome interlocking between the irregularities present on the surfaces.

Choose the correct option.

Q. If friction does depend on the surface area of contact, what if both the surfaces have similar atomic irregularities. Would it change

Consider the following statements:

Statement 1: Friction is caused by the interlocking of irregularities in the two surfaces.

Statement 2: The force of friction will increase if the two surfaces are pressed hard against each other.

Choose the correct option:

Q. Assertion :On polishing the surface the friction decreases up to a certain limit but increases beyond that. Reason: On polishing the surface, the irregularities are cut off but beyond a certain limit, the surface molecules exert strong attractive forces on each other.
