Question

Mark the correct statements about the friction between two bodies.
(a) Static friction is always greater than the kinetic friction.
(b) Coefficient of static friction is always greater than the coefficient of kinetic friction.
(c) Limiting friction is always greater than the kinetic friction.
(d) Limiting friction is never less than static friction

Answer 1

Answer ⇒ Option (b). Option (c). and Option (d).

Explanation ⇒  Coefficient of the Static Friction is always less than 1. This is the main reason why limiting friction is the maximum friction at the particular place.

Also, limiting friction is greater than or equal to the Static Friction but always greater than the kinetic friction.

Limiting friction which is the maximum friction of a place can never be less than static friction but it may be greater than or equal to it.

Hence, Option (b). (c). and (d). are correct.

Hope it helps.
