Please provide the figure for the question and the what to find in the question.

As for conceptual part,: As the rod is released the torque mg of the rod through the centre of mass provides the initial angular acceleration to the rod .The moment of inertia of the rod about its end is 1/3 ml^2=I

so, mgl/2=Ia(A is the angular acceleration).

Please provide the rest of details to proceed further in the solution.

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.
