Two objects, with masses m₁) = 1.65 kg and m₂ = 3.22 kg, attached by a massless rod parallel to the incline on which both slide, as shown in Fig. travel down the plane with m1 trailing m₂. The angle of the incline θ = 29.5° The co efficient of kinetic friction between m₁ and the incline is μ₁ = 0.226; between m₂ and the incline the corresponding coefficient is μ₂ = 0.127. Compute (a) the common acceleration of the two objects and (b) the tension in the rod. (c) What are the answers to (a) and (b) if m₂ trails m₁ ?

Therefore, the acceleration of the both the blocks is 3.45 m/s².

Therefore, the magnitude of tension in rod is 0.91 N .
(c)
It is important to note that if m₂ trails m₁, there will be no change in magnitude of acceleration. However, the tension in rod will become negative.

Three identical balls are placed on a frictionless horizontal surface touching each other. They stick to each other because of adhesive. Another ball of same radius and mass m is placed over the void created by the three balls. Find the forces applied by the balls kept on the floor to each other if the system remains in equilibrium.
