Work done would be equal to change in potential energy
Initially energy is 0but later energy will be mgl/2
We will see it from centre of mass

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.
