Physics · Laws of Motion and Friction
Object A (mass = 2 kg) is placed on a rough horizontal floor, and Object B (mass = 1 kg) is placed on top of Object A. The coefficient of friction between the floor and Object A is 0.1, and between Object A and Object B is 0.2. A horizontal force F is applied to Object A. Taking g = 10 m/s2, which of the following statements is/are true? (I) The two objects will move together if F = 10 N. (II) The maximum value of F for which the two objects move together without slipping is 9 N. (III) Object B will slip with respect to Object A if F = 10 N.
