Question

Q33. In case of static friction, the force of frictiondepends upon the(A) Roughness of the surface(B) Materials of the surface of contact(C) Weight of the body to be moved(D) None of the above​

Answer 1

Answer:

C) WEIGHT OF THE BODY TO BE CONTACT

Explanation:

Static friction is subtle because the static friction force is variable and depends on the external forces acting on an object. That is, fs ≤ μs N, while (fs)max = μs N. In general, μs ≥ μk. It is harder to move a stationary object than it is to keep a moving object in motion
