. Consider the following figure F a No of segments = N X One end of a polymer chain is attached to a rigid support, while its other end is being pulled by a force F. We want find an expression for F in terms of the length of the chain X. a. The partition function of the chain is, G Z (= e KBT) = |4nsinh| Fa kBT Fa kBT) Where, a is segment length, known as Kuhn length, N is the total number of segments and F is the applied force. b. Calculate the entropy of the chain. c. Calculate the end-to-end distance X as a function of the applied force.
