A student tries to raise a chain consisting of three identical links. Each link has a mass of m. The three-piece chain is connected to a string and then suspended vertically, with the student holding the upper end of the string and pulling upward. Because of the student's pull, an upward force of F is applied to the chain by the string. Use Newton's laws to answer the following question.
Find the force exerted by the top link on the middle link.
