Physics · Laws of Motion
Two objects A (mass = 2 kg) and B (mass = 1 kg) are placed on a rough floor with B stacked on top of A. The coefficient of friction between the floor and object A is 0.1. The coefficient of friction between the two objects is 0.2. A horizontal force F acts upon object A. Which of the following statements are true? (Take g = 10 m/s2) (I) The two objects will move together if F = 10 N. (II) The maximum value of F for which the two objects will move together is 9 N. (III) Object B will slip with respect to object A if F = 10 N.
