Three metal blocks A , B and C of masses 10 kg , 20 kg and 30 kg rest on a frictionless table in a line . A is converted to B and B to C by two pieces of string . With the help of a third string attached to C , the system is pulled to the right with a force of 60 N . Find the tensions of the first and second strings .

A horizontal force of 500 N pulls two masses 10 kg and 20 kg (lying on a frictionless table) connected by a light string. What is the tension in the string ? Does the answer depend on which mass end the pull is applied?
