Question

The limiting friction between two surfaces does not depend

• A. on the nature of two surfaces.
• B. on normal reaction.
• C. on the weight of the body.
• D. on height of the body.

Answer 1

Answer: (D)

on height of the body.

Limiting friction is the maximum friction that can be generated between two static surfaces in contact with each other. Once a force applied to the two surfaces exceeds the limiting friction, motion occurs.

The limiting friction between two surfaces does not depend on height of the body.
