Question

The statement given below is incorrect. Write the correct statement.

The rough surface offers very less friction.

Answer 1

1. The frictional force developed between the two surfaces in contact depends on their surface roughness.
2. Rougher the surface, the more will be the frictional force developed between them and vice versa.
3. The surface irregularities of the two rough surfaces lock each other which causes friction between them.

Thus, the correct statement is the rough surface offers more friction.
