The correct answer is (a) True

Easiest explanation: Following are the laws of solid friction :

1. The force of friction is directly proportional to the normal load between the surfaces.

2. The force of friction is independent of the area of the contact surface for a given normal load.

3. The force of friction depends upon the material of which the contact surfaces are made.

4. The force of friction is independent of the velocity of sliding of one body relative to the other body.
