Answer 2

Answer:

mark me as brainlist

Limiting friction directly proportional to normal reaction

As long as the normal reaction remains the same, the magnitude of limiting friction is independent of the area, and the shape of surfaces that are in contact. The magnitude of the limiting friction F is directly proportional to the normal reaction R between the two surfaces which are in contact.
