N identical carts are connected to each other using strings of negligible mass. A pulling force F is applied on the first cart and the system moves without friction along the horizontal ground. The tension in the string connecting `4^(th) \"and\" 5^(th)` cart is twice the tension in the string connecting `8^(th) \"and\" 9^(th)` cart. Find the total number of carts (N) and tension in the last string.
