Dear Gaurav.

If the hand of the stopwatch makes 1 revolution in minute and each revolution on is divided into 60 divisions then smallest division correspond to 60/60 = 1 sec
Hence least count = 1 sec

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.
