Two identical chairs, each weighing 7 kg, are stacked as shown. The center of gravity of each chair is denoted by G. The coefficient of static friction is 0.2 at B (the contact point between the chairs) and 0.35 at A, C, and D. If a force 10 N is applied at P, determine whether the chair can be at rest in the position shown without sliding. Justify your answer. -0.3 m--0.3 m- G. P В 0.2 m 0.6 m 0.5m Figure 4
