As per your syllabus, the maximum STATIC friction force on a block on a horizontal surface obeys which inequality?
Af_s = μ_k N
Bf_s = μ_s g
Cf_s ≤ μ_s N
Df_s > μ_s N
Answer & Solution
Correct answer: C. f_s ≤ μ_s N
Your syllabus: static friction adjusts up to a maximum (f_s)_max = μ_s N. Below applied force F, f_s = F.
