Question

The friction between two surfaces increases as: O the normal force between the surfaces decreases. O the normal force between the surfaces increases. O area between the surfaces increases O the coefficient of friction decreases

Answer 1

Option (a) is correct

Step-by-step explanation:

According to the laws of limiting friction, the friction force is directly proportional to the normal reaction acting on the body.

So more be the normal reaction more be the friction force.
