The tension at the right end of this rope is T: and that at the left end is T1_.[ gure 3}The rope has an acceleration amp: to the right. Complete the following equation for the force on the section ofthe rope of inertia m: taking the positive direction to be to the right. Give your answer in terms of T1, T2, and constants such as g.
